Ack! Why Won't It Sit Still?

My NaNoWriMo book wants to change again. It started out as a concept for a lonely man's journey back to life. Then it changed into a lonely couple's journey back to meaning from mid-life crisis. Now it wants to throw out all of that (and hours of plot outline) and become a comedy, a la Elmore Leonard or Dave Barry. The trouble with that (other than it may not fit my plot outline) is that I don't know if that would be easier or harder to write than the more serious book (although I was not really looking forward to being so angst-ridden for a month or more).

So, do I let it jerk me around like this? Or do I dig in my heals and insist that it stick to the plan? I'm hoping I can get started with the outline I have and maybe the writing will adapt to what works. I think part of the problem is that NaNoWriMo took care of my inner editor, but it didn't muzzle my inner marketing agent.

I'm up early this morning contemplating this and catching up on mail. I thought I would get in some writing, too. But it's time to get going to the paying job.
