Ok, there was a brief interlude for a phone call, but there was also work since I last posted. I'm approximately 3/4 of the way through the revision. I've realized that the last fourth is going to take a hell of a lot more energy than I have to give after doing the first 3/4. So I'm forcing myself to stop. I need to stop. Seriously.
But I've gotten really good work done today. Either that or it's garbage, but whatever the case, it feels like I'm on the right track.
