An "actual" profession? None come to mind... I'll leave it at "artist" and to add one with enough funding to do whatever he wants to create. So is that really a profession.. no, not really.
Back in college I skipped around trying different courses, all because I had no idea what I wanted and there was somewhat of an obligation to actually do something. That backfired because now I'm pretty much "too old" for college and I still have no degree. Well, to be honest, I don't aspire a degree, and in a way, the idea of "work" annoys me enough. Having a daily routine stresses me out enough to not even care about personal routines, let alone "forced" ones like jobs.
That being said, back in school I had a lot of sessions with therapists and counselors to let me look into what I actually want to be, as means of education. Based on a few tests I did everything pointed towards creative stuff; music, arts, photography... eventually writing. At some point I got suggested to look into journalism. That didn't work out, but at least I tried. So by tests, that came out. During sessions counselors already thought I'd be a severe case of "doesn't know what he wants because he doesn't care/like anything". Heck, one of em even thought I'd kill myself at some point because I'd be miserable cause of the inability to care/live for something as means of a job. Based on assessments of psychology, as well as some sessions, things pointed out like "cult leader", "revolutionary", "philosopher". Heck, at the proverbial yearbook (we don't have that in Holland) a few teachers agreed that I'd be a person most likely to commit murder or end up in jail... just because I had this "weird" mindset going on as a teen... not to mention a stare... (oh hi, aspie stare).
And to be honest, looking back now... IF I wanted to study something, I'd probably settle for philosophy, which will get me about as far as I am now, because the only thing I could do with philosophy is teach it in high school/college, which is something I don't really want to. Yes, I'd have a degree, but with that... myea, that's all I guess. Eventually I'd be more depressed because I actually have a degree, but people will not take it in high regard because... "hey.. what's philosophy... it's not like you can fix a car with that".
