Very few writers really know what they are doing until they’ve done it. Nor do they go about their business feeling dewy and thrilled. They do not type a few stiff warm-up sentences and then find themselves bounding along like huskies across the snow. One writer I know tells me that he sits down every morning and says to himself nicely, “It’s not like you don’t have a choice, because you do—you can either type or kill yourself.”
