Having won last year, I'm definitely doing it again. I've still got last year's novel I'm working on, so I'm just going to reset my word count to zero and work on the second half of it. Trust me, I've still got plenty I can write, and this story has been sitting since I was in high school. It's ready to get the rest of the way out.
I really loved the local write-ins we had last year, and our coordinators are the same people, so I'm looking forward to a lot of the same involvement again. As an added bonus, November is starting on a Friday this year, so I'm going to kick off NaNo with a huge writing weekend. Lock myself in a bedroom, only come out for necessities, and write. I'm better if I get a huge headstart so I can have a few days where if I slack off, I'll be okay.
