It took me until my mid-30s to feel like I had crossed a threshold in processing grief and trauma from my late teen years. I was capable of adult behavior long before then, but my concept of the world and how I fit into it (or don't) was still childlike in many ways on a fundamental level.

Like most such things, I'd expect this to be a spectrum, and I may be somewhat of a late bloomer. Regardless, I have a theory that there is somewhat of a protective effect operating here. Believing in a simpler reality which involved future wish fulfillment for me - however unrealistic it was - may have helped me survive. Coming to acceptance of what I see as a more accurate but far bleaker perspective required me to grow strong enough to sustain my will to live despite that perspective.

Biggest lesson learned: I could not do it without at least one other person (or more) who I trust almost 100% with all of myself. Realizing that going it alone is futile is definitely part of what I consider becoming an adult, and it can take a long time to fully accept that.

> Biggest lesson learned: I could not do it without at least one other person (or more) who I trust almost 100% with all of myself.

Its strange. The biggest lesson I learned was almost the opposite: I learned that the meaning of life has nothing to do with other people or their estimation of me. It has more to do with who you are when there is nobody else around. Other people often act as a sort of fun house mirror that distort and reflect back a false image.

Learning to be happy alone and seeing through the pleasant lies is absolutely vital to becoming an adult.

in_cahoots 6 hours ago | parent | next [-]

On the contrary, developing a deep relationship with someone very different than myself (different religions, native languages and countries, socioeconomic class, race, gender) has shown me the lies I've been telling myself all my life.

It's easy to identity lies and hypocrisy in others. But the brain has all sorts of tricks to prevent it from looking inwards; at least for me it prefers feeling rewarded to deep self-criticism. Finding someone who sees me and will happily call me on my assumptions, conditioning, and BS has been a great gift.

I'm not sure I'd have phrased it as "lies I've been telling myself", but I have a similar experience from a cross-cultural relationship, from mid 20s to early 50s. We had to work through conflicts more explicitly, with a lot more communication. Many things may be misunderstanding due to divergent assumptions, expectations, and even different body language signals.

I guess the "lie" exposed here is the way people can automatically believe they're seeing the truth of a social situation. It is easy to project false experience and motivation onto others. A more truthful approach recognizes windows of uncertainty around many encounters.

I think this applies to basic single-culture contexts too. Even in the same culture or the same family, we don't really know exactly what another person is experiencing.

Many seem cocksure that their social read is correct, and any grief is the other party's deliberate action. It takes a certain detachment to realize that your misreading of a situation may well be the genesis of a negative spiral, rather than a justified response...

in_cahoots 40 minutes ago | parent [-]

The social aspect is a part of it, but it's just the tip of the iceberg. So much of how we fundamentally see the world- the role of the individual vs society, luck vs skill vs determination as being important for success, what defines a 'happy' life- is determined by our own conditioning. By seeing someone else's perspective you start to appreciate that there aren't many 'first principles' in life.

Take a simple example, marriage. If you're a Millennial you were probably brought up to think marriage is for love, and should produce kids. Depending on your orientation and enculturation, the wife is 'supposed' to stay at home or 'supposed' to have a career. We don't question the basic outlines of what a marriage looks like, unless you happen to be a part of the polyamory or fundamental religious communities, in which case you probably take those standards as being the ideal.

My husband's entire family had arranged marriages. Seeing their relationships gave me a new perspective on what a marriage can be, and forced us to be intentional about what parts of our culture we bring along. It's not that we're doing marriage 'better' than anyone else, but when you can't assume anything about what a marriage looks like you have to really examine it in detail.

From an evolutionary standpoint what would be the benefit of the brain looking inwards and constantly questioning itself? Certainly lower animals mostly just go with what instinct tells them, maybe with memory of prior experience in the larger-brained ones. Most people also seem to operate on their feeling of "common sense" without much reflection, at least in my observation.

When what you think matters. An animal that questions its belief "there is no tiger behind that bush" and finds a tiger lives longer than one that doesn't.

slfnflctd 6 hours ago | parent | prev | next [-]

I feel like we need both. There are mental/emotional experiences I have on the regular which there is no point in trying to communicate to someone else but still bring me great benefit. We need to value our alone time, absolutely.

We also ultimately derive pretty much everything we most value in life from our interactions with other lives, which is why I think it's so important to develop high-trust relationships with at least one or two other people so we can continue to grapple with the fact that we all have different perspectives, weaknesses and strengths and can usually learn more and get significantly more things done when we cooperate than when we're running solo. Which requires trust.

YMMV, of course. Some people can go build a cabin in the woods and live off the land and spend all their free time meditating and be perfectly happy. But that's not most of us. And even those people eventually get too old to keep taking care of themselves.

mapontosevenths 4 hours ago | parent [-]

> We also ultimately derive pretty much everything we most value in life from our interactions with other lives

This implies that almost everything you value is something transient that can, and one day will, be taken away. If not willingly, then by death. Doesn't it make more sense to have a few core values that don't depend on others and then build relationships and all the rest upon that foundation?

To steal from Alan Watts, lets use an example. Imagine a whirlpool in a clear stream. It has great beauty and takes intricate forms as it dances a whirls. You sit beside it and enjoy watching it for hours.

Now ask yourself is it the particular group a H2O molecules that make up the whirlpool that you love? If so it will be gone in an instant, and each moment for you will become another in a series of great losses as the molecules are swept away by new ones. Is it the pattern the water makes that you love? No, the pattern itself changes every moment as well. The change itself is part of what mesmerizes you.

What you love about the whirlpool is something deeper, and more fundamental, something that change can't take from you. That's the thing you have to build your appreciation of life from. Other people are just the molecules and ripples.

> Some people can go build a cabin in the woods and live off the land and spend all their free time meditating and be perfectly happy.

I would argue that a man who can't stand to be alone with himself is either a bad man who is a good judge of character, or an incomplete person.

I don't mean that everyone should go live alone, just that everyone should be able to. You're probably right that most people can't do it, but the majority is often wrong.

array_key_first 4 hours ago | parent [-]

It depends on how you view life. In my view, the purpose of life is to build relationships, love, and understanding. I can be alone, but loneliness forever is, in my mind, indistinguishable from me not existing. Tree and the forest and all that.

Yes, relationships die because everything changes constantly. Nothing is stagnant. But then again everything dies. Ultimately, I want to impact others and be impacted.

elliotec 5 hours ago | parent | prev | next [-]

This is an interesting perspective but I think both are necessary. At different times in my life (perhaps correlated to the "brain eras," though I'm still a bit skeptical of the details here) I've needed others for development and contentment, and at other times, I've needed to focus on self-love and solo happiness as you describe.

Whatever your "meaning of life" may be, it's not the estimation of you that other people have that is important, but we are incredibly social creatures. Life is really not possible for individuals of our species without some level of society and community. Even Christopher Knight - the North Pond Hermit in Main who lived alone without human contact for 27 years - survived by burglarizing cabins and camps and was eventually reintegrated into society.

I guess my point is this is a dialectic. Both can be true, and both are true. The "trust almost 100% with all of myself" might be debatable, but "I could not do it with at least one other person" seems kind of obvious, as does "Learning to be happy alone is vital to becoming an adult."

thisislife2 3 hours ago | parent | prev | next [-]

Both of you are right - OP is right that life does become weary when you have to do everything yourself, with no help or support from others - and that includes emotional support. We are social creatures, after all. You are right that we as adults also need to learn to be comfortable / content with our thoughts when we are alone with them, and not define our happiness through our relations. We all need both solitude and company, to introspect and grow.

kulahan 3 hours ago | parent | prev | next [-]

We're a social species. It's not a funhouse mirror, it's just another side of your personality. No human can even survive in isolation, so the solitary side of you is an exceptionally small part of who you are.

The danger with self reinforcement is you can convince yourself of almost anything.

There are many selves, and you will never know your true self. Because you can only process yourself through your own mind, which will perform transforms, regardless of how hard you try not to. And maybe there isn't even a true self, only perceptions.

I've been buying socks from Sketchers for years now. It's the only brand I buy. They're not amazing, but I get holes in my socks so fast I don't really care. At the very least, all my socks match, even though I probably have some that are 8 years old and some that are 2 weeks old.

Can you elaborate on the last point? As someone going through a very hard time with my wife at the moment I’d love any words of wisdom.

sillysaurusx 7 hours ago | parent | next [-]

I’m going to go against the grain here.

The parent’s advice is toxic and mistaken. It’s a road to codependency. I’ve been with my wife 20 years, married 15. I would have said the same thing they said — I can’t do it all on my own, I need someone else.

Rubbish. And also dangerous rubbish. I’ve been weak for a long time simply because I hadn’t taken myself seriosuly. I literally believed that I couldn’t do it alone, which was wrong.

It was unfair to my wife to use her as an emotional support when she didn’t want to be. She’s been there for me a lot over the years. But when you tell someone that you can’t do it without them, it’s no longer their decision, and that’s unfair. Both to her and to me.

Please read Codependent No More, and especially Lost in the Shuffle by Subby. (I’ve identified a lot more with the latter.)

The point is, it’s okay to be having a rough time with your wife. Let go. Let her do her own thing. Stop caring so much. It’s okay for her to be upset and not want to help/have sex/go to an event/involve you/whatever the problem may be. The reason it feels rough is because you personally let it feel rough. Once I adopted that mindset, it became so much easier. And ironically my marriage improved.

Meds are also important. Make sure you’re on a good dosage of antidepressants if you need them, and a mood stabilizer. I recently started Latuda and dropped Seroquel per my psychiatrist, and it’s been night and day.

Lastly, keep trying to talk to people about your problems. I ended up reaching out to a random person on Twitter. They were kind and to my surprise happy to listen. It was one of the main reasons I was able to get through it all. The best person to talk to is a therapist, though I’d be happy to listen till you can find one.

You’re strong. You need to believe that. And you’re strong independently of your family or anyone else. Give yourself credit for getting as far as you have; that part has been important too.

Apparently “codependency” means something significantly different to what I guessed (which was interdependency, depending on each other). https://en.wikipedia.org/wiki/Codependency:

> In psychology, codependency is a theory that attempts to explain imbalanced relationships where one person enables another person's self-destructive behavior,[1] such as addiction, poor mental health, immaturity, irresponsibility, or under-achievement.[2]

> Definitions of codependency vary, but typically include high self-sacrifice, a focus on others' needs, suppression of one's own emotions, and attempts to control or fix other people's problems.[3]

SoftTalker 3 hours ago | parent [-]

I've heard codependency described as being dependent on others being dependent on you.

It probably has some rational basis in child rearing, it will benefit survival for the parents to be deeply dedicated to supporting their children, to the point where they receive a psychological reward from that dependency. But unhealthy when it comes to adult relationships, at least beyond a certain point.

jswelker 6 hours ago | parent | prev | next [-]

Just want to point out codependency--especially if you read Codependent No More--is not about being dependent on another person. That is dependent personality disorder perhaps.

Codependency is better described IMO as secondhand addiction. It was coined to describe the symptoms of people who live with alcoholics and other substance abusers and the destructive coping patterns they use to survive in the addict's wake. The codependent does not depend on the addict. In fact closer to the opposite.

Upvoted just for mentioning the book though. It was life changing for me.

butlike 3 hours ago | parent | prev | next [-]

Yes exactly. I came to the same realization. After 5 years, I've realized I can do it alone (but it's more fun to do it with someone else).

Make sure the other person adds to the fun, so to speak.

slfnflctd 6 hours ago | parent | prev | next [-]

I get what you're saying. A therapist is one of the types of people I had in mind, although that obviously isn't an option for everyone.

I agree that it's important to be able to have your own independent autonomy to properly function in a healthy relationship, especially a romantic one.

The point I was trying to make is perhaps more subtle than it came across, namely that webs of trust between humans (e.g. 'community') are, in my view, essential to being a fully actualized adult. If you aren't close to anyone, I think that means something is wrong which deserves further inspection, particularly within yourself.

sillysaurusx 6 hours ago | parent [-]

Sorry for the somewhat harsh words. You have a point. The problem is that it’s way too easy to fall down the codependency rabbit hole when you start thinking of it as “I can’t do X unless someone else Y’s”. It was true for me, and I just wanted to make sure it wouldn’t be true for the poor fella going through marriage problems.

The trick and the trouble is that it’s easy to acknowledge the importance of being independent, especially in a romantic relationship, vs actually doing that in practice. After your 30’s your friends start to fade away, and one day I woke up without any except my wife. That was clearly a degenerate situation unfair to her, and expanding your social circle is something that should be done independent of whatever relationship you happen to be in. In fact, needs to be done.

anon84873628 3 hours ago | parent [-]

Another complication / nuance is that, of course you should be serving and supporting your partner (and vice versa)! Its part of what makes relationships rewarding. They're not always 50/50 in all aspects.

The trick, as you say, is to know when that is crossing into something unfair. When it goes beyond something like who does the dishes or makes the most money into supporting the other person's core identity. Or when it becomes unsustainable / exhausting for other person. Identifying these issues can be difficult. It requires both partners to be in touch with their feelings and able to communicate openly.

KittenInABox 7 hours ago | parent | prev [-]

There is a huge difference between acknowledging that humans are an inherently social species that usually needs comfort and psychologically benefits from an intimate relationship and straight up codependency, where you violate the boundaries of each other and thereby take away psychological safety.

sillysaurusx 7 hours ago | parent [-]

I agree! The point is, don’t use your wife for your comfort and psychology benefits. Use the other people in your life. Especially when you’re having marital problems.

I'd hit up a solo therapist. I went through a hard time with my wife and turns out she just sucks. Be warned that she sucked a lot worse in the divorce and states differ wildly in how biased they are against fathers if you have kids.

It was helpful to figure out some of my stuff and deal with a bunch of trauma.

Or else books / online communities. I can't recommend using ChatGPT for this kind of help but it can be used to validate your experiences, provide a different experience, and if you ask it, point you in the right direction.

For example, if you explain it (or Reddit) an interpersonal situation it can break it down and e.g. point out certain behaviours or boundary crossings.

But I would be careful, as these chatbots will by default put you in the right, even when you aren't.

lazide 7 hours ago | parent [-]

Even therapists are a mixed bag - and some are legitimately dangerous - but in my experience at least 100x safer than a chatbot or just books.

If for no other reason than a chatbot can’t call you out on your bullshit, because it has no hope of telling what is or is not bullshit. And that is key. And has no actual feelings, remorse, license to lose, etc. etc.

mattbettinson 2 hours ago | parent | next [-]

Yeah I like LLMs to dump feelings/stuff and explore different angles of viewing it. It’s like CBT by tons of angles of attack

ToucanLoucan 5 hours ago | parent | prev | next [-]

I found a chatbot helpful when I explicitly requested it, in detail, to argue the other person's side with me. I basically approached it as "I want advice on this particular conflict," I explained who the other party was, I explained my best summary of the situation as a whole, and I went back and forth.

I found it cathartic because I could basically argue with that person about it, without asking that person to do emotional labor or be subjected to my criticisms of where I felt they were wrong. Ultimately I landed on several points I did eventually go to that person with, I dropped several others that the chatbot pointed out weren't really something it was fair to criticize them for, and I think our friendship is overall better for it.

I don't think there was anything revolutionary there, it's basically journaling with an LLM, but it was more efficient if nothing else.

Edit: I would also caveat that I've attended a lot of therapy, individual and couples, so numerous concepts that some people may not know, things like emotional labor, boundaries, healthy communication, etc. are already very familiar concepts to me. So, I wouldn't recommend a chatbot as a FIRST stop? But if you've attended a lot of therapy and already know a fair bit about how your own feelings work, I think it can help, as long as you explicitly request that it doesn't just glaze you continuously.

Consider posting on https://interpersonal.stackexchange.com/ . Note however that they don't allow posts about identifying problems - e.g. Why am I having a hard time with my wife?. Rather, you are expected to know what is your specific problem and seek solution to that. Don't go to Reddit - the standard advice there will be "your wife / husband is a toxic partner, run and get a divorce".

slfnflctd 7 hours ago | parent | prev | next [-]

I have had many difficult times with my current S.O. over 15+ years.

Everyone's situation is different, but I can say that in even a semi-healthy relationship, time heals many wounds, greater mutual understanding grows, hard edges can soften and people will often surprise you. You can also learn things you could improve about yourself which you were previously blind to. The sense of stability this reinforces is immensely helpful.

On the other hand, I also have an ex-- and while I wish I would have ended that differently in hindsight, it did need to end for my mental health to improve. If you are with someone who abuses you, cannot be reasoned with and never admits fault, it is wise to plan several exit strategies.

catlikesshrimp 6 hours ago | parent | prev [-]

Every person is different. Some people don't need a stable relation, some people *can't have* a stable relation, some people thrive with it.

Every relation is different. A successful relation is built when both side are compatible.

What does compatible mean, though? Some relations are swingers. Some relations follow strict religious rules. Some people need taking a beating, and I don't mean an erotic one. In None of this cases I am meaning they are codependent, and then there are successful codependent relations.

The only constant I have seen is that every successful relation has discussions, fights, momments when they considered separating. And there is compromise, in every case.

I am sorry I don't have any specific advice. Good luck

I did not feel fully adult until my parents passed on. I was in my early 40s at that point. Then I knew that there was no fallback; it was all up to me.

A person becomes an adult once they take responsibility for their own actions and the consequences thereof. Many people never reach that status, regardless of age.

It's not so tersely defined as that, I don't think. It's kinda like wax in a lava lamp of information. Some gloops, the others glop, until eventually you gloop and glop and feel confident. Rigid labels and markers on the spectrum don't really hold universally true, I'm finding.

Weird, for me its the complete opposite. I accepted to live alone for the rest of my life because a) I am undesired and I wont make a move. b) I barely met people I would even consider it being worth talking to, I need to feel equal on a cognitive level and not a lot of people match that requirement. I either feel lesser or above.

hvs 7 hours ago | parent | next [-]

You certainly don't need to have someone in your life -- as someone who married late and has two kids now I sometimes look back on my long period of begin single with fondness -- but I would also recommend being very honest with yourself. Very few people are totally undesirable and expecting others to meet some predetermined standard is very common among people that don't interact socially very often (I speak from experience). While I'm lucky that my wife is very bright (and in many ways much smarter than me) the most important thing that she has given me is new perspectives on life and seeing that it's more important to be kind and helpful than smart.

It's very hard to see outside of our early conditioning without outside perspectives. We may have a vague sense that we might not have been given the best tools for social development (we may even be brutally aware of it), but having someone that has the skills that we are missing is often more important than that they have equal skills in areas we are strong in. Having a good partner can make you realize things about yourself and open you up to things that you never even realized were there.

zwnow 7 hours ago | parent [-]

Yea I get that. A partner would be nice but in 30 years of my life I met 2 women I liked. I am extremely self aware in that regard. I am repulsed by modern dating and dating apps and I dont get myself "out there". I also have way too high standards but I cant just ignore them. Also being chronically depressed does not really help either...

So I just accept my situation and I don't want to change my ways as I am content with how my life currently is.

anon84873628 2 hours ago | parent [-]

It's good you are so self aware and can accept your situation to find a level of contentment.

No partner is perfect so being in a relationship requires evaluating tradeoffs and deciding where you can compromise compared to your ideal. To do otherwise or expect someone (or yourself) to change is unfair to them. Unfortunately sometimes we think we can deal with something but ultimately can't - that's part of the self discovery and vulnerability/heartbreak of relationships (because we can of course be on the receiving end too). Really you have to be willing to embrace a person's flaws and take long term joy in doing so, and also have gratitude for them doing the same.

So if you know all that's not really for you, then good move on your part.

I often talk indirect because lots of things are obvious to me and dont need to be explicitly verbalized in a conversation so I am expecting my conversation partner to keep up with my pace. I know its possible because I met people that are able to do so. Although most are not. I dont talk to teach or to be taught. I value teaching and learning but regular conversations are not a place I learn from or I teach at. I've grown up with a lot of trauma and a lot of topics simply have no meaning to me, that's why I regard a lot of conversations as pointless.

For me to regard a person as worth talking to it requires them to either have lived through similar trauma, be a master at some craft, have some (to me) interesting hobby or a lot of life experience to talk about. I simply dont want to talk about someone's favorite sports team or some trash tv stuff. A lot of topics are also above my head so I zone out easily.

Assuming they are, just for the sake of the discussion: what kind of answer do you expect to this question? You think someone who is arrogant has a theory of why they are so and are willing to share it? I would expect they are mostly blind to their own arrogance. Can be useful to point it out.

Your A) is a fallacy. Carefully consider that one. Fore B) You're mad projecting onto other people. I used to do this and frankly, I came across as a complete ass a lot of the time. People are super complicated and no other person can figure them out completely, let alone as quickly as you think you are.

zwnow 2 hours ago | parent [-]

I know that people are complicated, but to me 90% of complications do not, and will never matter.

People having people problems bores me so much. I am the type of person ready to irrationally throw their life away in the blink of an eye, I guess I am looking for people like that.

As an example I started tattooing myself without ever having done it before. My arms look like shit but it doesn't really matter to me, I wouldn't change a thing.

Additionally, my social energy is drained very quickly. Having people around me would make me feel trapped. I am nice to every person I meet irl, it would surprise me a lot if people considered me an ass. I am the silent type.

Also no. A) is not a fallacy. In 30 years I was approached once. Whenever I used dating apps I wouldn't get any matches. All I had were some charming talks with friendly women that I initiated when having a night out, but thats about it. I sit in my room all day doing stuff on my computer.

The parent comment was talking about having trauma. They were probably once in a position where they very much weren’t healthy, and through the gradual gaining of awareness came to the realization that they needed help.

If I had a broken leg, it’s obviously not going to help trying to fix it myself. Why would it be a stretch that unhealthy thought patterns, which by their nature are self reinforcing, not require an external influence to help break the feedback loops?

It's kind of interesting to compare this to Ptolemy's eras. In the Tetrabiblios, Ptolemy argued that man went through seven ages in his life, each associated with a different celestial object.

1. Infancy --- The Moon. Since the Moon waxes and wanes more rapidly than any other celestial object, this period is characterized by the fastest development.

2. Childhood --- Mercury. As Mercury is the fastest of the planets, at this age children have the short attention spans and flit from one thing to the next.

3. Youth --- Venus. Starting around puberty, a man's mind starts to become focused on love.

4. Young Adulthood --- The Sun. A man comes of age, he starts to think about his work and people begin to take him seriously.

5. Middle Adulthood --- Mars. In his mid 30s a man's demeanor becomes more severe. He realizes he has certain goals he would like to accomplish and there is not much time left to achieve them.

6. Maturity --- Jupiter. By his mid 50s, having achieved what he can in his life, he has arrived at a position of authority in the community. He has gravitas and respect.

7. Old Age --- Saturn. By his late 60s, he starts to decline physically and mentally.

It is worth noting that this exact sequence (the Chaldean sequence) of the seven classical celestial objects follows the same paths as the Serpent of Wisdom coiled about the Tree of Life in the Hermetic Qabalah. This is the western analogue to the Hindu notion of Kundalini, which shares the same serpentine symbolism; both of which represent the process of the psychological maturation of man.

See Liber 777 Col. VII [0], Key Scales 3 through 9 inclusive. Also note that Key Scales 4 through 9 in Col. XCVII, excluding Saturn in old age, correspond to the "Ruach," "soul," "mind," or (one could say) "post-bicameral ego" of man.

>At around the age of 32 the strongest overall shift in trajectory is seen. Life events such as parenthood may play a role in some of the changes seen, although the research did not explicitly test this. “We know that women who give birth, their brain changes afterwards,” said Mousley. “It’s reasonable to assume that there could be a relationship between these milestones and what’s happening in the brain.”

>From 32 years, the brain architecture appears to stabilise compared with previous phases, corresponding with a “plateau in intelligence and personality” based on other studies. Brain regions also become more compartmentalised.

--

I felt this 32-year-old shift, but later (now 43). I joke with friends that I was a bone-head like most males until about 30. Joke yes, but feels right.

Prior to 30ish, I was more insecure. Lacking in emotional intelligence. My conclusions from my experience, not projections from what I've read about that time.

My career and relationship history reflect that switch-flip in a way. Only during the second half of my 30s did I begin to feel more secure and more confident in my career, despite not achieving some outrageous senior position or level of income. That career is now in a better and more measured place - in which I recognize what I do well and what I don't do well, and don't beat myself to a pulp for not having "it"

Only in my 30s did I robustly embrace the power of compromise in friendships and relationships. Now I'm near 10 years married (and happy, most of it, let's be real) with two wonderful kids.

And now I'm much capable of reasoning with my anxities, emotions, and insecurities. Do I still ruminate? Yes. Do I still react? Yes. But I know how to redraw situations to reset my in-moment feelings and/or avoid unecessary negative action.

The work never ends, friend.

Try this. Think hard about what you think "it" is. Is it CEO? Making $1M a year? Making $5M a year? Healthy family? Etc.

I think what you realize in the brainstorm is you have some of "it" already. But something's missing.

So, then ask this question: can you change your situation to attain that missing thing? If so, how? And if you aren't doing that, why? Ask why again. A third time.

Inaction is a very easy way to get stuck overthinking "it" when you might get that thing just by changing/trying your situation to the best of your ability.

I am articulating what seems linear but in reality its messy and not very linear. It's work and it's trial and error.

But more than ever, I'm ok and comfortable with the construct of my life. I don't make anywhere near what I hoped to make. I'm not an executive. I don't now think that I NEED (and am missing) those two things to fufill my life. (those are examples, I have others)

I've always thought that I'm just extremely late to mature. I'm 36 now and haven't really felt like I sort of "get" things until my early 30s. My 20s were full of learning experiences, failures, and addiction to doing whatever the hell I wanted. I got a puppy with my wife at 29 and it felt like my life was over. This all really makes a lot of sense to me. It also makes me wonder why the human body rewards young parents when their brains are just simply not fully finished cooking. I couldn't have imagined raising a child at 22 with the way I acted and how important freedom was to me. I would've simply been a miserable father.

It's always been financially complicated for most people. The notion of a nuclear family prospering with a single income was mostly only possible for a limited slice of the US population during a few decades post-WWII. If you take a broader historical view that was a brief anomaly.

And it's really weird that anyone would think of something amorphous and uncertain like climate change as a reason not to have children. Even the unlikely worst case scenarios are still going to have less impact than the major wars and plagues that our species has lived through. Some people just lack a sense of perspective.

Yes that model has been inverted.

The family used to tax the grown or mostly-grown children in the form of farm labor. The government in many prior centuries taxed like 2-5% total and the rest was intrafamilial support.

Now it is flipped on its head. Everyone else's families tax your child for their social security, socializing the benefits while still you retain most the costs privately.

Thus tragedy of the commons situation. Why make that investment when you can just tax everyone else's kids and rest assured of your own social security, if they don't pay it you can just have them tossed in a cage or their assets seized, no need to have children yourself.

This is a toxic myth and acts as excuse to blame extrinsic factors that won't see change by the time you'll need them to, even if they can be fixed. Economic life today can be a lot more complicated for middle class professionals and skilled laborers, but they were only ever a fraction of the population in the first place, and families in tougher circumstances than today's middle class folk figured out how to navigate the cards they were dealt.

Emotionally, it legitimately sucks if you come from a comfy middle class background, and have a career that you believed should have been good enough to deliver the life you remember your parents or grandparents having and now doesn't seem to be. It feels unfair and disorienting, maybe. But the fact is that middle class lifestyle is gone for now, and if it does manage to get restored, that restoration will take a generation or two to come.

In the meantime, you have to figure out how to adapt and live that more modest and "more complicated financially" lifestyle. It can be done. Lots of people have been doing it for a long time. Along the way, you'll probably discover that lower class folk who never had the luxuries of your parents and grandparents in the first place were not seeing the world as something they had to "suffer in": they lived in homes, but often with more people in them. They traveled, but more infrequently, less glamorously, and with more pragmatic rationale like "visiting family" than "seeing the world". They had parties, but served simpler dishes on less fancy platters. They had "child care" when two parents worked, but got it by exchanging favors with family or neighbors instead of sending half a paycheck to a prestigious daycare. They laughed, they drank, they had kids. It's not a world of suffering to just not have some luxuries.

Yes and I think many of us remember childhood with rose-colored glasses. My 1970s "middle-class" parents had one car. My mom had to drive my dad to work and pick him up so that she could have a car during the day. When my brother and I were older and in school she worked part time. We lived in a simple ranch-style house. We almost never ate out or went anywhere out of town. Entertainment was going outside and finding something to do. Something like going to a movie was a rare treat. I think of it all fondly today, never with a sense that I had missed out on anything.

Today many young people would consider that life to be stifling, boring, or "suffering" but it was fine. Kids really don't care as long as they feel secure.

There’s major inflation in middle class expectations. People earning median income are expecting a very upper-middle-class lifestyle. A house bigger than their parents owned with nicer finishes, two new cars, frequent travel, eating out constantly, etc.

My parents were on the upper end of middle class when I grew up and we lived in a home with carpet and laminate countertops. Now everyone wants hardwood floors and quartz and more square footage, too. A lot of folks are driving cars that cost a year of their take home pay. Cost of living is too high but expectations seem to have risen even faster.

Indeed, it is society's expectations that are hard.

I moved to the middle of nowhere after my kids were born. One day I let my child walk home "alone" from school, for the portion that is on our own property, and of course as soon as you do that a fucking Karen will randomly pop out of nowhere, and start interrogating the child. It is like clockwork. You could be 100 miles from civilization and as soon as you do something someone somewhere disagrees with, a fucking Karen (and even in a minivan, down rugged rural dirt roads, how the fuck did she get there?) will magically be there that exact second with a cell phone at the ready to call CPS. Thankfully I was able to stop her before that happened, as I was actually watching from behind the bushes, which in itself is shameful but saved my ass.

I suspect it's a cultural thing as well, with most (all?) wealthy cultures veering towards individualism and working. Whereas with previous generations, the grandparents and environment would be more involved in raising children and educating the new parents.

But I also feel like people grew up or had to grow up earlier back when. My parents were married, bought a house and had kids on the way by their mid 20's, when I was that age I had just about finished my education and started my first fulltime job, it'd take another decade to buy a house. Buying a house / getting a mortgage is a major commitment, and I think you'd get a big boost of adulthood / personal development if you do that in your mid 20's.

Early twenties family formation bring the norm was more of a postwar thing. The guys that came back from the war really did have to grow up fast (seeing your best friends getting blown up at 18 will do that), and they essentially had zero desire to have racous twenties filled with dating around and traveling and soul searching. They'd had enough chaos already, and were all extremely eager to settle down into a peaceful family life immediately upon their return home. The age of family formation has slowly crept back upward since then, and historically, in normal peaceful times it's usually been late twenties.

I would encourage you to look at the medical costs of children in the US. My children's braces alone will cost ~$7k-10k over the life of each of them, with insurance, and to do without will cause irreparable oral damage into adulthood. Certainly, this doesn't apply to other developed or developing countries, but to say "you just need to feed them" wildly differs from reality. You're just ignoring suffering at scale by saying "it'll work itself out." It doesn't, and I can provide pages of citations, grounded in data, to support this assertion. Also, having served a short stint as a Guardian ad Litem to advocate for children going through family court, I have anecdotal observations as to failure scenarios of failures to adequately provide for children, both materially and emotionally.

Supposedly for those 10s of thousands of years in parts of Europe people formed tribes and had some communal living, that is, in a long house, maybe 50-100 yards long 10-20 yards wide, with walls and roof forming a semi-circle. So, women and children got their socialization, security, lessons, skills, not merely from a couple, a bonded husband and wife living just as a couple, but from the tribe as a whole. I.e., now, for a lot for a person to learn and have, including shelter, we are depending heavily just on the mother and father.

I realize that sounds silly but it really does work. A lot of emotional behavior is muscle like and setting aside intentional practice will lead to longterm change.

1. Set a trigger to engage in the practice like "When I hang out with my kids immediately after the work day"

2. Do the practice. Try to be empathetic to your kids small daily issues. At first, like all newish things this will feel silly but over time it will feel natural.

Obviously try to be genuine. If your kids plight of someone snatching their favorite toy or whatever doesn't move you, don't force it. Just try to practice visualizing yourself in their place. Don't go "fake empathetic kid tone".

But of course, I could say that I've never had to live through war and don't think that I could really say that I've built the fortitude that that experience gives you, so the point might be moot.

As a childless person, I believe this is a societal problem, not a biological one. We've broken apart the tribe and made just two people (at most) responsible for most of child rearing.

Smart take. Parenting used to be more communal in some ways. Now it's up to two (maybe) working parents to deal with kids.

43-yr-old parent of 2. I love them. They're amazing. But there are so many challenging moments. So many.

In those deep/profound moments of stress, I try to remind myself that the only thing I really need to do is stay calm. Allowed to have emotions, course.

But to execute some level of calm really helps resolve so much of what you experience.

Strangely enough, I think I do understand. As near as I can tell, life's two greatest pleasures are 1. Love (both loving and being loved) 2. Voluntary hardship

No, I'm not insinuating anything.

The authors charted human brain and divided it into "eras" where they saw significant changes based on age. Major life events can affect brain structure, and becoming a parent is one of the most important adult life events. Becoming a parent in early 30s is common. Just these facts combined mean that being in early 30s correlates with brain changes somehow. The authors explicitly mention that they know about this, and that they didn't control for this it yet.

Back to your question, I never said anything about maturing. It is a well-known fact, that female brain changes after childbirth. There is also research that suggests that first-time fathers brain changes too. This doesn't necessarily mean becoming more mature.

Just when the "brain doesn't finish developing until 25" nonsense has finally waned from the zeitgeist, here comes a new pile of rubbish for people to latch onto. Not that the research itself is rubbish, but how they name/describe the phases certainly is. The "adolescent" and "adult" phases don't have any correspondence to what we normally think of as those developmental periods. That certainly wont stop anyone from using this as justification for whatever normative claim they want to make though. It's just irresponsible.

Seems a stretch to use this as the basis of any radical change like raising the voting age to 32 (although maybe it supports reducing the minimum presidential age from 35 to 32!), but it does perhaps suggest looking at what kind of soft-paternalistic structures might help “adolescents” make better life choices.

For British Sovereign there is also no limit, any particularly young Sovereign has effectively delegated to a council of regents historically. In practice this is also unlikely - although in theory of course we are two untimely deaths from a 12 year old taking the throne.

Just as a thought experiment: what if the threshold for having a vote was tied to paying a positive amount of personal income tax, and the weight of each vote was proportional to the amount paid? How skewed might such a system be? My first reaction is that in countries with high inequality, the wealthy would disproportionately influence the outcome. However, on the other hand, if people avoid or minimize paying taxes, they would lose the power of a weighted vote, which theoretically could incentivize paying taxes in full.

Such a plan would codify an oligarchy into law, rather than the mere de facto oligarchy we have now.

You're uneasy because you're a frequent advocate for policy positions that most people tend to be weary of once they've accrued some amount of life experiences (although the experiences and speed of acquisition differ from individual to individual) hence anything that casts shade upon the decision making of the youngest adults is a potential threat to your goals, if only a theoretical and circuitous one at that. If such policy positions do not survive life experience are they worth advocating for? 100yr ago people has been treated by the world around them as adults for at least half a decade by the time they got to vote at 21. Why not do the same today?

Regardless, specific policy implications are totally beside the point.

The problem with this "well you're not akshually an adult until X" stuff is that it is basically a re-hash of long out of fashion "women are hysterical, blacks have big muscles and small brains" type crap from 200yr ago that was used as a justification to continue preventing these people from finding their own way in life unbounded, consequences and all. First off, the logic is flawed and self referential, of course housewives and slaves couldn't adult, they never had the opportunity to gain the experience, same with 22yo college kids you're measuring today. Removing the racism and sexism by simply applying it to everyone doesn't change the flawed logic. But that's not even the big problem. The big problem is that at a societal level you're reducing the number of person-years available for full adult capacity work and productivity. You can solve this with coercion (state, social norms, etc), but people are less productive when they're not working for themselves so you're still handicapping your own society. A society that does not encourage people to develop and become adult and achieve and produce at full capacity as quickly as possible (which is likely a different timetable in an agrarian society than an industrial one, details left as exercise for the reader) WILL eventually be outcompeted by one that does, though a head start may buy time.

Thanks for sharing the longitudinal brain-development framework from the Cambridge study. However, I don’t see strong direct practical value for an individual or educator in the life-stage breakdown (~birth–9, ~9–32, ~32–66, ~66–83, ~83+) beyond broad observation.

In contrast, frameworks from learning theorists such as Vygotsky, Piaget, Bloom, Gagné, Maslow, Bruner and Kolb provide more explicit actionable guidance for parents/teachers (e.g., scaffolding learning in the “zone of proximal development”, designing spiral curricula, applying experiential learning cycles).

My perspective guides me to prefer the pragmatic actionable frameworks. That help someone guiding children (or students) set norms, limits and scaffold growth in daily practice.

I do like the conversation that's cropping up here though from this article. A lot of lovely self-reflection.

Exactly this. With a comfy life, you can mature later. The more hardships and adversity one must overcome the faster that maturation happens. Particularly so when the hardships put one on an abnormal path.

Losing a close relative or a job is normal adversity that everyone will go through but not everyone has. Going through those other things while having a different philosophy or life ethos than those around you, thus also causing you to prioritize and pursue different things in life adds a different layer of challenge. That causes you to have to figure stuff out on your own and thus contributes to maturing in a different manner and at a different rate.

There is nothing to engage with. I think tersely. Some researchers could learn.

I find it annoying that a large part of research is the obsession of taking a perfectly smooth, gradual phenomenon and introducing artificial boundaries, sometimes even with formal labels.

But I'm sure this fantastical finding was great for somebody's career.

crazygringo 4 hours ago | parent [-]

Meaningful categorization is a necessary and foundational aspect of science and understanding in general. We categorize matter into categories such a solid, liquid, and gas, because this has meaningful consequences beyond merely temperature.

If you think the categories in this article are useless, you're going to need to justify that. Aging is well-known to encompass phases with nonlinear transformations, such as puberty or menopause.

So what you find "annoying" is actually a building block of science. And while disagreeing in a particular case is certainly valid, you're going to have to either present evidence to the contrary, or else find weaknesses in the particular methodology used.

So there's plenty to engage with. But you're not doing it, so your comments are just snark with no value.

For example, here - is this *caused* by genetics, or is it because in today's society this is about the age when you have finished your schooling and first working experiences and have simply less to learn?

I know my examples simplify the reasoning, but the question about causality still stands, I think.

At age 58, going on 59, I'm feeling an alarming decline in physical (luckily not mental at this point) ability. Sure enough, men have relatively abrupt aging events at about 44 and 60. I hope that's what it is and it's not still coming and making things even more pathetic.

So I have, on average, another 7 years until I'm officially a typical old man? Great, just great.

But I can vouch for the earlier milestone. I grew up as a socially challenged geek with nobody to tell me that I'm just wired differently and it's not my fault, I didn't somehow not do my homework, that I'm not like the cool kids. Right around age 30 I had this epiphany... this is how I am! Instead of always looking for someone or something to teach me how I think I should be... just embrace what, in fact, I am. If I'm a geek, then just live my life best as a geek. The resulting increase in self-confidence did help socially. So just another prerogrammed "adulting" threshold? Maybe.

In my late 20s/early 30s I was under water on my house, not getting paid enough, and had a small child. It was clear that I had to step up and "be a man." Which, I intuitively think had a bigger effect on me than simply getting older.

That is an absurdly small sample size to make such a conclusion.

It seems this age range could at least partly be culturally attributed. In modern industrialized life, many people don't have to "grow up" until a later age. At the risk of generalizing, people have more support from family, friends, and society at large.

Is the forming of those neurons based on some natural law, or is that people just haven't had to live the experiences that do so until their 30's nowadays?

As far as I know, forming neurons isn't something that "just happens". It happens due to catalysts in life. In pre-modern society, and indeed most likely in under-industrialized nations today, those catalysts, those experiences, would happen earlier. As others mentioned, there is a clear correlation with the typical age in which modern society gets married, settles down, and has kids.

I wonder what that era age would have been 200+ years ago.

What you end up getting is people ~10 years into an exciting career where suddenly they can't perform or cope as well as they used to. But they can also be in a pretty senior position by then and be pushed out of their comfort zone.

The problem with such reports (the studies themselves method-wise etc are in general fine I guess, but how the results are interpreted and disseminated is the issue) is that unless we find some specific correlations with behavioural and such measures, it makes no sense to give these kind of meanings such as "adolescence", adult mode", behavioural/mental/cognitive matureness or whatever cultural or other norms one may think a "mature/adult person" should abide to. Especially since these abstract topological measures, while interesting, are not that trivially linked with real outcomes in a causal sense, and instead of eg simply reflecting rather environmental or other changes in a person's life.

At 18, people have not learned right from wrong, love, death, loss, true responsibility to someone else. Sure, someone at 18 have gone through these things and it hopefully helps guide them in life, but it may not penetrate the brain as a life lesson yet. The brain is basically a blur up until your thirties, because you don't have any of these experiences to compare to until you encounter them again.

That's why as you get older you start to understand what the heck is happening in your life, because you finally have multiple experiences to compare to. Then you can finally understand what is meant to be traumatic and what is right and wrong. The first time you went through something you were basically numb to the experience.

So you aren't an adult until your early 30's and you are an old slow guy not worth interviewing less than 10 years later.

Where did you get that from? The article mentions changes at age 9, 32, 66, and 83.

It's just the popular wisdom these days. Companies tend to deprioritize hiring engineers in their 40s, especially if their overspecialized. At face value, Companies want high-energy 20-somethings that they can mold into their specialty. More likely, they know that 20-somethings expect a far smaller salary.

So you aren't discussing the article at all? And you imply mythrwy isn't either?

I had kids and finally settled into a career at 33. It certainly forced me into adult mode after this.

I just met up with my Brother-in-law and his friends for our yearly gathering. All of them are in their 30s and none of them are in what I would consider 'adult mode'.

They are all un-married/no kids, barely scraping by, partying every weekend/wasting money on weed and booze. Certainly no careers (mostly retail, some unemployed and still living with parents).

I wonder if these numbers will change with the new generation, because so many are not having kids or getting married.

This sounds more like an anecdote of “my brother-in-law and his friends are losers” more than any indication of a trend.

The median income almost doubles between age 23 and 35.

There's definitely a transition associated with becoming a parent - that is well documented.

When I think about my friends and friends of my relatives, what GP described appears to be the norm - also among the educated and in the upper-middle class. They often identify themselves as "dog parents".

Did you read the article (or hell even the title) before commenting...?

I know plenty of people that had kids in their 20's - still didn't 'grow up' until their 30's. Just because they're not partying anymore doesn't mean they still don't act like adolescents when navigating complicated situations they're in (because they're had kids before they were necessarily 'ready') compared with someone in their 30's. I would argue that taking away that time in your late 20's where you can more easily make mistakes and try new things (while also having a bit of stability in terms of money) before having kids will lead to less maturity rather than more long term.

Probably not, the comment read more as a way to rant, self-boast, and judge others' lifestyles than anything insightful.

This is another psychology narrative put forth as a quantifiable scientific finding.

Q: "Is this based on a clearly expressed scientific theory?"

A: "Be serious -- it's just an idea, a narrative."

Q: "What would constitute a basis for either statistical validation or falsification?"

A: "You're confusing psychology with science. That's naive."
