 The negative thing about digital is you have to constantly work on it. The great thing about digital is you get to constantly make it better. So you're not frozen. When I print a book, it's either good or bad. I'm stuck with it. It's on the shelf for the next 40 years. It's a printed book. When I put something out in the digital world, I can change it tomorrow, and I can change it the next day, and I can change it the next day and make it better as I go along, and I will.
