What to major in...what to be when i "grow up"

First it was a film director, then it was a singer/songwriter, then music composition, then film scoring...now I can't decide between any of those. I cant even think of anything else that I'd like to be.

My girlfriend AND my mom suggested that maybe I should think about being a nutritionist/chef since I know a lot about different foods and nutrients...and I've cooked several meals all from scratch. Most of them being vegetarian (more specifically piscetarian) so that it is "eatable" for my girl.

The thing about me is that if I take up something that I love or have a passion for...my mind can easily change because of the schooling or all the hard work. In that way I'm quite childish.

All I know is that I want to love what I do, be able to use creativity, and not be completely limited in the work.

But for now...I'm still undecided.
