I am having a great time. And my doubts aren't about societal norms; I've directly gone against societal norms at least twice (quitting my first well-paying, well-respected job to start a games company when I was 21, and quitting my most recent well-paying, well-respected job to focus on acting and filmmaking). I'm OK with that.

My doubts come from within. It's more about my own expectations for myself. For example, at my age and with my background, am I a fool for not trying to start a VC backed startup like everyone else? I guess there's a strong FOMO element in my questions.
