When you start the edit phase, it's like raking cold stiff ground. Then the ground begins to soften and you warm to the cognitive task in hand.
I'm doing two kinds of edit: looking through the entire book for habitual phrases, phrases that I use to keep myself writing, and which work in talks, but not so well in books. And slowly reading through the whole thing for content and form.
Hyperobjects is much better than it was two days ago, which is very pleasing. All permissions but one are now in hand, which is excellent.
