I work slowly; it’s always difficult — it’s nearly always difficult. I’ve been writing steadily, really, since I was twenty years old, and now I’m eighty-one. My routine now is to get up in the morning, have some coffee, start to write. And then a little later on, I might take a break and have something to eat and go on writing. The serious writing is done in the morning. I don’t think I can use a lot of time in the beginning; I maybe can only do about three hours. I do rewrite a lot, and I rewrite and then I think it’s all done, and I send it in. And then I want to rewrite it some more. Sometimes it seems to me that a couple of words are so important that I’ll ask for the book back so that I can put them in.
