When I pick up a pencil, that this is a rough draft. This is not going anywhere, and no one's going to see it. You have permission to make all the mistakes you want. It signals freedom to me, and it signals mistakes. Then when I put it on the computer, a different part of my brain kicks in and I really evaluate every single word and sentence and make decisions. I like that step of polishing while I'm rewriting the entire thing, not just cutting and pasting. Really putting in every word and making a decision: is this something I can stand by?
