My schedule is absolutely my own. Usually, I write all day, but if I want to go back to the studio in the evening, after dinner, I don't have to sit in the living room because someone else has been alone all day. I don't have to sit there and be entertaining or amusing. I go back out and I work for two or three more hours. If I wake up at two in the morning - this happens rarely, but it sometimes happens - and something has dawned on me, I turn the light on and I write in the bedroom. I have these little yellow things all over the place. I read till all hours if I want to. If I get up at five and I can't sleep and I want to work, I go out and I go to work. So I work, I'm on call. I'm like a doctor and it's an emergency room. And I'm the emergency.
