I am the kind of writer who rewrites and rewrites. I am very eager to correct everything. If you look at one of my manuscripts, you can see I make many changes. So one of my main literary methods is repetition with difference. I begin a new work by first attempting a new approach toward a work that I've already written — I try to fight the same opponent one more time. Then I take the resulting draft and continue to elaborate upon it, and as I do so the traces of the old work disappear. I consider my literary work to be a totality of differences within repetition.
I used to say that this elaboration was the most important thing for a novelist to learn.
