Can you call yourself a marathoner if you make like the hare and take a shortcut?
I'm seriously considering (meaning: I've pretty much decided) to adjust my Nano goal to a personal goal of 25K words. My current word count sits at 18,540. 25K seems doable.
On reducing my commitment to "Nano-lite", I feel a new sense of peace. The brow is unfurrowing, the brain is losing that vise-like tendency that was squeezing the life out of all my characters (and not in the good way), and I feel ready, willing and able to get back to story creation...which is a long way from word spewing.
