I ain't never written a novel before. The longest thing I've written is my Masters thesis, which took just a bit longer than a month (um, 2 years), and was only 25 000 words. Keeping with the spontaneous spirit of the event, I decided not to waste one of my golden story ideas on something that will end up being crappy and rushed, so I just closed my eyes while I took a dump and waited for my brain to generate a novel (in both senses of the word) idea. What came was a jumble of westerns, a murder mystery, and squirrels. Hmmm...you know, brain, that doesn't sound all that good, but I'll write down what you tell me to and see what happens.
I started late (on the 5th of November...remember remember), so I'll have to write 2000 words or so a day. Yeah. Right. I'm destined to fail, but it's the participation that matters more than success. Maybe I'll work my way up to actually completing NaNoWriMo next year, but for now, I'll just give myself an A for effort.
You should write a novel too.
