Well, first of all, did you write to “The End”? Because if not, then you may have survived, but you’re not done. You must get through to The End, no matter how rough it is (rough meaning the process AND the pages…). If you did not get to The End, I would strongly urge that you NOT take a break, no matter how tired you are (well, maybe a day). You can slow down your schedule, set a lower per-day word or page count, but do not stop. Write every day, or every other day if that’s your schedule, but get the sucker done.
