I consider writing an athletic activity: the more you practice, the better you get at it. The reason you keep your hand moving is because there’s often a conflict between the editor and the creator. The editor is always on our shoulder saying, “Oh, you shouldn’t write that. It’s no good.” But when you have to keep the hand moving, it’s an opportunity for the creator to have a say. All the other rules of writing practice support that primary rule of keeping your hand moving. The goal is to allow the written word to connect with your original mind, to write down the first thought you flash on, before the second and third thoughts come in.
