First (last?) NaNoWriMo

Maybe I'm a psychological self-flagellant but I signed up for NaNoWriMo this year. I have never written a novel before but  have played with the idea of adapting a TV pilot of mine. Seems like a good time and low stakes scenario to indulge this itch. 
I also need to complete the first draft of my new feature script in November so I'll be a crazed person by December.
