"I haven't written a novel or something that long, because I really am improvising all along and the story is growing new limbs to do what it needs to do. So there's very little planning. There's a little planning where I say, "Well, it looks like I'm going in this direction, ok, good." But there's very little forethought or intellectual justification: "Oh, look, I'm putting in a theme park because that represents dystopian America!""
