Dreams

Have you ever really wanted to do something, like a job, even though you really didn't know a single thing about that subject? I kind of feel like that...because my dream job would be to be a professional composer for a movie or video game company. unfortunately though, I have never really composed anything of any girth. So really, I'm basically just trying to do a job I know nothing of. I just wonder if I'm super crazy in this dream? or if others feel that way...
