At the risk of sounding like a broken record, and parroting everything that everyone else has ever said about this topic, I'll keep it short.
Yes, I am participating in NaNoWriMo this year. If you feel like you have a story in you that you just want to get out, this is a great way to do it. If you don't like writing, or you don't have a story in you, then that's fine too. Either way, I should have a new 50,000 word story in draft by the end of the month, and if you want that for yourself you can come along for the ride with me. We can even help each other along the way!
