My revision methods are chipping things away and moving them around and trying to get things right. I'm also open in my own writing to failure. I want to fail. I want to go to a place where I don't know what I'm doing, where maybe I'm lost. And in that uncertain space, I make decisions, and I know all those decisions are going to change everything else. And at a certain point, you just come to a place of rest. In revising, you reduce your options so that nothing is possible, and you just think, I can't change this anymore because I've already passed that decision point.
All the preparation in the world doesn't avail you if you can't make that imaginative leap and put yourself in the position of the characters you've created, to imagine what it's like to be somebody else.
