Dragon software (you talk, it types). I'd tried my hubby's version a couple of years ago but really stumbled over my desire to edit as I went. Three NaNo wins, and I've pretty much overcome that tendency for first drafts. It worked like a charm and really upped my word count.
The book's not finished, but I've been glossing over some sections I know have to be included as I'd been waiting on expert input from a family member. My goal used to be to beat NaNo before Thanksgiving. Now my goal is to finish the book.
