This is actually my case, some people saw me present a topic I love to talk about would say I'm an extrovert. But in reality I rarely speak a thing in a debate about a problem I don't really care about, so people call me an introvert. I gradually don't care about the opinions anymore and just want to preserve my energy for the things I really care about.

Yes, a realization I came to awfully belatedly. As a kid, all those speeches and essays where I struggled anxiously with topics I didn’t know much about or care much about, and bullshitting is not one my strengths or preferences. Decades later, I’m rather more aware and more opinionated, but my days of addressing groups of people seem to be long over.

What got me as a kid was both not having strong opinions and worrying about whether my weak opinions would be acceptable to the other kids. Music for example was a bit of a minefield as I worried whether what I would suggest would be something others would approve of. Eventually developed much stronger tastes where I would be happy to stand by it if others didn’t like it.
