I wanna be a writer and I tell people that all the time. :P A game journalist, though. I have a blog for that now, and I work for a game website. :P (... For free.)
You should totally be a comedy writer if that's what you want to do. And some day you can meet Tina Fey and be all like "YOU MADE ME WHAT I AM!" and she'll be all "DON'T YOU DARE BLAME ME!"
