I got put on jury duty, which is where I learned how to write.
The whole trick is to make it feel like you're spying on real people's lives as they get through the day. When I'm writing, I have to trick myself as a writer. If I consciously say, 'I'm writing,' I feel all this pressure and somehow it doesn't feel as real as when it doesn't seem to count as much.
I had various jobs, I taught a SAT class, I was a bartender, I had a day job at an office and was making short films. I got grants from NYSCA and NEA for an idea, which later became 'Huckabees,' about a guy in a Chinese restaurant who had microphones on every table and heard every personal conversation and would write perversely personal fortunes.
When I write an email where I outlined a whole scene, it just came out of my unconscious, it comes from a deeper place. The same thing happens when the actors go, take after take, and just get lost in it. When you're in a house, you don't think about being in the house; you're just there.
