Wait. isn't that why people go to art school in the first place? Because they don't know what they want. Art school is a waste of money for most people. I think it looses it's appeal when your friends who went to "real school" start getting well paying jobs and you learn to paint pretty shit.
After I graduated college, I dicked around for a year or so. then I opened up a children's art center. I am 23 and I teach art during the day to kids. I do whatever the fuck I want the rest of the time.
Don't stress over life. Laugh at dickheads. Be honest. Do your thing.
But! If you do go to school, you will end up with a much bigger and better (for the most part) music and movie collection.
