I was once doing a question and answer period with the novelist Jane Smiley in a bookstore and someone asked us what our processes were and Jane said hers and then I said mine and Jane said, "Well, if I had a student like that I'd force him never to write like that again because you could never write a novel in the way that you write poetry."
