Final tally of my unofficial NaNo attempt:
So I did not reach my word count goal. BUT! I wrote more than I expected and made serious progress on my WIP. Better, I like what I wrote. I may have met the 20k mark, but during the last two weeks of the month my attention was diverted by holiday/family stuff and writing entries for a micro fiction contest.
Because the contest entries were all-new material, I counted those words in the final tally as well.
Altogether, I had a LOT of fun during this first attempt at NaNo. By this time next year, I really really really hope Blackbird is finished and I've moved on to the query phase.
