Not sure if this is motivating or demotivating.. but I know I guy who had a habit (generally) of writing a novel every 11 days. He's a professional writer though. He actually writes them in 10 days, takes a day off, then starts again. So... as long as you have 10 days left, I think it's always possible to finish, . Granted, I think he writes for at least 6 hours a day... butt in seat writing. He also manages a company in his non writing time.
