‘I am not an early-morning person; I don’t like to get out of bed, and so I don’t begin writing at five A.M., though some people, I hear, do. I write once my day has started. And I can work late into the night, also. Generally, I don’t attempt to produce a certain number of words a day. The discipline is to work whether you are producing a lot or not, because the day you produce a lot is not necessarily the day you do your best work. So it’s trying to do it as regularly as you can without making it—without imposing too rigid a timetable on your self.’
