" Writing is one of the loneliest professions in the world because it has to be practiced in this very separate private world, in _here_. Not in the mind; in the imagination. And I think it is possible that the writing of fantasy is the loneliest job of the lot, since you have to go further inside. You have to make so close a connection with the unconscious that the unbiddable door will open and the images fly out, like birds. "
