"My characters write my stories for me. They tell me what they want, then I tell them to go get it, and I follow as they run, working at my typing as they rush to their destiny. Montag, in 'F. 451' wanted to stop burning books. Go stop it! I said. He ran to do just that. I followed, typing. Ahab, in 'Moby Dick,' wanted to chase and kill a whale. He rushed off raving off to do so. Melville followed, writing the novel with a harpoon on the flesh of the damned Whale!" (Busch, Frederick. (1999). Letters to a Fiction Writer. New York and London: W. W. Norton & Company)
Makes it sound easy, hunh?
