Novelists—especially novelists who paint on a broad canvas—are generally not given to undue anxiety, I think. The task is so enormous that if we ever really thought about what we were letting ourselves in for, we'd never begin. Early on we learn to worry only about what we do today. If I get my two or three pages written on Monday my day's work is done. It's useless to worry about Friday or four years from Friday. Pages need our attention; books take care of themselves.
