I've always written. When I was in school, the only teacher who ever liked me was my creative writing teacher. I used to enter poetry competitions, and I don't think I ever lost one. So I had the idea for a while of being some kind of poet.
I think a big part of 'American Idol' that scares people and actually has, I'm sure, stopped people from trying out is the fact that you do have to do things that are necessarily not your genre.
