I'm wrapping up the wee little RTF book I'm writing, to turn in Tuesday to get all gussied up for QC1. It's going quite well, and actually much faster than expected. I have a chapter that's just the odds and ends pile; and then chapters that are pretty much single-topic. I'm having luck working on the single-topic chapters until I get tired of that, and then I work on a section for the odds-and-ends chapter. Then when that's done, if I'm not too tired, I can go back and work on the single-topic chapter.
