“But it’s what I call “The Valley Filled with Clouds” technique. You’re at the edge of the valley, and there is a church steeple, and there is a tree, and there is a rocky outcrop, but the rest of it is mist. But you know that because they exist, there must be ways of getting from one to the other that you cannot see. And so you start the journey. And when I write, I write a draft entirely for myself, just to walk the valley and find out what the book is going to be all about.”
