Although I'd pretty much decided it by Monday, I'm going to now officially declare that I've thrown in the towel on NaNoWriMo this year. I don't think I've written on my story since Friday, and I don't think there's any chance I can bring up the word count fast enough to get 50,000 in November.
This isn't a bad thing, however. I now have the full set of notes to carry on writing a story I really like. Without worrying about my writing speed, I can now pull the story together and let it improve as I consider all of what could possibly happen.
It may even be a good thing, I never finishedThe Speed of Darkness until a good while after NaNoWriMo.
