NaNoWriMo is all about pounding out words until you get to 50,000 or more. The biggest mistake one can make is to start thinking of whether the words thus pounded really belong in the novel(la) or not. I committed that error and went downhill by removing stuff I just know won't be in the final story.
Other nanon-ers are telling me how wrong I was to do that. Well, I'll keep trying to write things that actually belong in the book. When I'm still short of the 50K near the end of this month, I may retrieve the junk and shove it back into the manuscript. I'm proud, but not that proud.
