>Dr Bloom spoke about how your overall mood during college is a good predictor for how happy you'll be as a person throughout your life.

Welp, I guess I'm dead then.

>around 25, making personality changes MUCH more difficult

Maybe it's just me but my personality keeps changing every year or so, based on the positive and negative experiences and challenges from living abroad alone, having to always adapt to new stuff to stay mentally, financially and socially afloat.

I assume it's different if you spend your whole life in the same place you grew up in with the same people doing the same things. Maybe the brain checks out from the repetition.

>avoidant behaviors that limit my social ability

Move aboard to another country where you don't speak the language.

If it’s true then this is a propensity and not a rule.

My mood in college was suicidal. My mood by my 30s was better than most people I’ve ever met (sans hiccup from a year of no sleep with a newborn).

Looking back my horrible mood in college was probably caused by isolation, no sleep, high pressure course load, and too much alcohol. And I’ve noticed my mood drops dramatically when I get it in my head that I need to be more successful, at any point in my life.

It's probably you! My personality has been basically the same since I was 4. I also live abroad and have for the past 5 years, though, so I guess I just lucked out and got a personality that works well in most conditions and with most people.
