Help! I'm just so indecisive...?

I would just appreciate some honest advice. I'm 21 and I have no idea what to do with my life. I'm lucky that I have my parents to help me but we're not rich and I need to figure out what I want to do and fast! I'm running out of time! I just can't focus on one thing. I hate math. I love music, I love art, I love reading... what can I do that I can make money in that involves these things? My parents are angry with me because I can't just pick something and go to school for it. After highschool I threw away 3 years working and getting in debt and now i'm trying to go back to school. I figure being a teacher would be nice cause it would give me time to do other things, but I wouldn't want to work with small children... I just.. I want to be everything! I want to be a photographer, I want to be a dancer, I want to be a teacher, I want to be a writer... I want to make GOOD money... I want I want I want... :-( What I need to do is be realistic and pick something!
