As I've said before, I think this is a very worthy exercise, and I wish everyone the best of luck. Push forward and write! One of my fondest memories from my unpublished days was trying to finish THE WAY OF KINGS during the Thanksgiving holiday at my mother's house. Did 16k in 24 hours, not to win NaNo, but because I was so invested in the story and wanted to finish the climax.
About five months later, I got a call from an editor in New York wanting to buy ELANTRIS. KINGS would be the last novel I would finish before knowing that I was going to break in. I still feel an occasional nip of longing as I remember those carefree days, when I could simply WRITE and not worry about reviews, deadlines, or revisions which were due.
Interestingly, despite four or five years being involved in NaNo, I've never actually 'won' it. I write 50k often, but I'm always in the middle of a project when November arrives, and don't want to start something new--so I just write on my current project. Still, I'm with you in spirit.
Try to beat me, if you can. I'm at 10k words as of midnight, but may have to stop to do the Mistborn 3 copy edit next week.
