1) Music coordinator for film and television, Los Angeles
I am not even joking, this is an actual job: creating soundtracks for movies and TV. I'd spend part of the day negotiating with record companies for broadcast rights, the other part of the day listening to the scads of free CDs I've received in the mail from up-and-coming bands, and every night go to a concert. I'm still in awe of the fact that people get paid for this.
2) Actress, National Theatre, London (the RSC or the West End would be all right too; I'm including them in this category.)
Okay, so the American accent might be a problem. But I'm thinking that once I broke into the scene, myriads of playwrights would begin writing in the role of the quirky American girl into their shows so that I could be in them. Or else someone would just teach me to pull off British.
3) Casting director, National Theatre, London
I would get to go see plays and showcases every night, probably with killer seats, for the sole purpose of scoping out talent so that I could recommend people to directors and help with their casting choices.
4) Entertainment journalist, Paste magazine. (Rolling Stone would be fine as well. Really, I'm not picky.)
I'd review music, books, movies, etc., which means I'd get a bunch of them for free, and
5) Pediatric endocrinologist
Treating kids with hormonal disorders-- diabetes, growth hormone deficiency, thyroid problems, etc.
