I personally find that I’m often extroverted and sometimes introverted. I think it’s less helpful to think of this as a static character attribute and more of a mood. I think the parent is pointing to the idea that by labeling something this may reinforce it such that introverts become more introverted by finding validation in books like Quiet, for better or worse. It’s a part of an interesting discussion that doesn’t seem to get talked about much at the very least.

I like the definition of extrovert and introvert that says that extroverts are regain their energy by being in group whereas introverts regains there by being alone. According to that, I'm an introvert, I need my alone time so that I can recenter myself and recover my energy. I do feel drained when being in events with a lot of people.

But, that doesn't stop the fact that I do like people, I like organizing parties (or rather I don't particularly like the organizing but I like the result of having organized parties and having close friends) at my place and regularly invite friends. It's just that after that I'm exhausted and I need some alone time to recover. So being an introvert doesn't imply that you shouldn't make effort to reach out to people or that you won't enjoy being with others. It just means that having some alone time is necessary to recover.

I defined introversion as stable underlying trait that doesn't change regardless of how many social activities one participates in. I described it as similar to "right-handedness" being a stable trait regardless of new skills acquired with the left hand: https://news.ycombinator.com/item?id=27794484

However, if some people want to define "introvert" differently as only a temporary mood, I can't argue with that but I wish society came up with a different label that describes introversion-the-unchangeable-stable-trait.

Sure, but it all depends on whether it's causing you problems or not. There are different ways to life to one's satisfaction. If you're having problems, you should change things up and push through discomfort and friction or just try things. But if you found a balance that works, then it's fine if that involves being alone a lot and just occasionally meeting people. Depends also on phase of life. In college freshman year you probably want to force yourself to go out regardless of how you feel, to establish some contacts and friends. Once you have a circle, it's fine to just live the way you enjoy it actually.

I'm an introvert. I occasionally love going to a big conference/event, including regularly speaking at them. I find it incredibly fun, and incredibly exhausting. It's fun and rewarding enough to do anyway despite being exhausting. I know other people who find it energizing.

There are people whose feelings about it vary, but there are also people whose feelings about it are consistent but they do it anyway, and that sometimes gets mistaken for variability.
