Two days of Nanoing and I'm close to 3000 words. Hoping to do more later, and hit up a write-in in San Francisco tomorrow.
The tenor and pace of the writing is really changed with the volume being paramount and deadline looming. I'm not doing what I usually do, the tinkering and fixing of the previous piece, and that is pushing me to go further faster. It's good. I'm also making handwritten notes for ideas on what to write on when I get the BIC (butt in chair). Stockpiling these notes makes me feel surer that when I do sit, I'll be able to do it and not stall around.
I'm pretty sure I wouldn't want to start writing a novel this way, but getting into a current project and getting it up to speed and a greater volume works well, for me.
