Two years is a long time, but I say accounting. Don't follow your dreams, they just make reality seem disappointing. I kid, but seriously think about something you wouldn't mind doing the rest of your life and go with that, but be thinking about what happens once you graduate throughout your college career (what I mean by that is "for God's sake, go into accounting so you have a job"). Or start now.
