Two Steps Forward, One Step Back

I've been hard at work, writing my NaNo novel. I got all the way up to 8,100 words, then decided to chop a bunch at the end and change things around. I was back down to 6,300 words, but now I'm back to 7,400 words. Considering I was hoping to write at least 2,000 words a day and it's the 6th already, I'm way behind. I am going to have to plant my ass on the couch and get typing.
