"One basic thing the mind does is generate thoughts. The problem is: it's hard to settle it down. The mind has a tendency to wander and drift off or barrage us. Even before we get a first thought—the ones that carry vitality, that are connected to the body—we are lost in critical second and third thoughts: "I can't do this writing. There's a sale on tuna. My kids need attention. I have nothing to say. I'm boring." These divisive, churning thoughts are telling you a lot, but not what they are actually saying. It's an indication of nervousness and energy. It tells you you want to writing bad, but at the same time are terrified to write."
