I've quit writing screenplay [adaptations]. It's too much work. I don't look at writing a novel as work, because I only have to please myself. I have a good time sitting here by myself, thinking up situations and characters, getting them to talk - it's so satisfying. But screenwriting's different. You might think you're writing for yourself, but there are too many other people to please.
