Writing a book is like rearing children—willpower has very little to do with it. If you have a little baby crying in the middle of the night, and if you depend only on willpower to get you out of bed to feed the baby, the baby will starve. You do it out of love. Willpower is a weak idea; love is strong. You don't have to scourge yourself with a cat-o'-nine tails to go to the baby. You go to the baby out of love for that particular baby. That's the same way you go to your desk.
