I stayed up until 1:30 last night, working. I never do that, but I was on a roll, and didn't realize how late it had gotten. I now have a draft of a 16,000-word sample chapter, with only a few holes: two sets of legal citations to look up, one book to skim for references to one of the subtopics, and revising the chapter intro and conclusion to reflect the changes I made. But all in all, I'm cautiously hopeful.
48 hours and counting. Any good thoughts and encouragement (or cookies, or offers to read chapters... or cookies...) will be really, really appreciated.
