Creative writing, Lit, and history
(of course, all subjects where you don't make any money unless you become a mega-star - just my luck).
I always admired people who made fictional worlds, like JRR Tolkien or George Lucas.
Same with lyricists - it's something I admire that I wish I could do myself and want to know how to do.
And history is fascinating because you see how the world came to be. It's like a story, just like fiction.
And because I can't think of a question right now, and think this is a good one anyway -
same question.
