Are you still writing? You mop the sweat from your brow. You check the calendar. Yep! Three more days to make it to the winners' circle. You're typing furiously, willing your characters to do something, say something, anything.
Mine did, and guess what? They wanted to make it a happily-ever-after tale and it just got too pleasant for everyone. Boring. So I turned it all on its head, and they had to solve for themselves how to get out of the mess they found themselves dumped in.
It worked, and I finished just before Thanksgiving. Whew! I am still in recovery. We will meet again, on the other side (of NaNoWriMo).
Break a leg! (but not your typing fingers)
