That's Onward Part 3 with an exclamation, not Onward Part 3(factorial). I don't think there will be six parts but if there are, then I haven't thought that far nor have I decided to start writing on it.
That absurdity aside, yeah, I'm going to finish my book. I don't know how many words, how many pages or whatever it will take to get there but I've got some sketchy notes, I've got some good thoughts and most importantly, I've got the bug again.
I don't think I was burnt out by NaNo. That's the pace I want to be able to maintain. I think it's sustainable, at least over a little while, if I can a) overcome hardware failures, b) overcome my love of video games and c) keep it to a time when it doesn't affect my work or my family. Kim's scrapbooking table is right near the computer desk I used for the majority of NaNo, so it's not like I'll be completely ignoring my wife.
It's all there for me. Now I just need to pick up the pen (and put down the controller) and start writing again.
