When I'm writing a novel, I'm dealing with a double life. I live in the present at the same time that I live in the past with my characters. It is this that makes a novelist so eccentric and unpleasant.
Writing can be bad and still be part of something good. That 'art' is really 'artifact,' Exhibit A, Exhibit B, of something else: a person's whole experience and life. And that always there's the chance that this will fail. That things will not work out.
