I'm not going to make my word count for NaNoWriMo. I'm disappointed, but this has been visible in the distance for awhile now. I just couldn't keep up. I started out so strong, but I couldn't keep going on a sleep deficit and I got sick, and couldn't kick it - it kept coming back. Still, I know it was doable, I just made a choice not to sacrifice to the level I would have needed to to hit the 50,000. And I'm good with that choice still.
While I don't have as many words as I might like, I'm very happy with the words I have. At month's end (I am going to keep writing until the end even if I can't hit my words) I will switch gears to revising the previous book. I've been doing a lot of exercises on character, and I think I can use what I've learned to help significantly in the revision process.
The plus side of not pushing myself into burnout is that nearing the end of November I'm still excited about writing and my story, and not sick to death of it. I'm calling it a win. Not an official NaNoWriMo type win, but a win in my progress and growth as a writer.
