I really do believe that chance favours a prepared mind. Wallace Stegner, who was one of my teachers when I was at Stanford, preached that writing a novel is not something that can be done in a sprint. That it's a marathon. You have to pace yourself. He himself wrote two pages every day and gave himself a day off at Christmas. His argument was at the end of a year, no matter what, you'd got 700 pages and that there's got to be something worth keeping.
