Most publishers are happiest with a successful novelist when he or she writes the same book every time. They don’t care if he bathes only on the summer solstice, drinks himself into a stupor every day by 2:00 P.M., lives in sin with a llama, thinks SpongeBob SquarePants is the greatest actor of his generation, and spits on the floor—as long as, at the keyboard, he can slavishly repeat himself manuscript after manuscript.
