The author seems to on the one hand have a lot of ambitions, but on the other a case of ADHD (or modern-day tech-caused attention deficit) where they end up hyperfocused down a rabbit hole on a regular basis. I have no answers for that, because even medication probably won't make people focus on their mid- to long-term goals. That said, being a New Yorker writer, theater troupe, and all the other things they mentioned, they're probably fairly successful in their life beyond the lofty goals they've set themselves. Which may not be their true calling actually, but more of a "this is what people I look up to have done".
