Forum Friday: What has the Nano experience taught you?

Just one more day of November and the madness that is Nanowrimo!

Whether you’ve reached the magic 50,000 or not– whether it’s your first time doing Nano, your twenty-first, or you heard what Nanowrimo was and ran away screaming in terror– with every draft comes experiment, progress, and lessons.

So what did you learn? What has Nanowrimo taught you (this year, collectively, or otherwise)?
