I'm not worried about the amount of words I cranked out, because I did work a fair bit today; I spent a bunch of time revising, and I think I have a much better handle on my protagonist's voice now. He was kind of coming across as a single-minded jerk before; I think he's more appealing now, and more multi-dimensional. There'll be more work to do in that regard, but at least I think I'm headed in the right direction. That's a big relief.
