Only about 20% of people who sign up for NaNoWriMo actually complete their 50 000 words. What does that tell you about writing and people? To me, it says that a publicly-declared intention does not ensure follow-through on a goal, and that setting the goal is not the problem. It takes more than "just get started, then keep going" to write a novel, and those 80% of people who fail will attest to that. I think NaNoWriMo needs to look to those 80% of failed participants and ask them what went wrong. Did they run out of steam? Was their idea not sustainable for the length of a novel? Were they derailed by some personal disaster, or could they just not commit to the time it took every day?

PS - Not enough attention is paid to failure stories these days.
PPS - Which is a pity. We could learn so much.
