1. NaNoWriMo is an outside force acting on your writing. What I mean to say, is that often we give ourselves deadlines to make things happen in our writing, but there is no one to enforce those deadlines but ourselves. Now some of you may have great writing self-discipline, but for the rest of us, this is important.
2. The NaNoWriMo community has some great advice, exercises, videos, and forums to help you through writing snags and roadblocks. Whether these are issues with grammar, setting, character names, plot, or almost any other writing issue, I guarantee other writers in the community have experienced it and have something to say to help you through it.
3. NaNoWriMo celebrates your writing accomplishments, every day for 30 days. This, I feel, is the most important part of NaNoWriMo. Often, writers write and write and edit and submit and get nothing in return but criticism and rejection. Every word is precious during NaNoWriMo and something to celebrate, and I cannot describe the feeling of accomplishment those days when you make your word goal, let alone at the end when you have a proto-novel in front of you.
No matter if you do the "hard-core" NaNoWriMo of 50,000 words in 30 days or dial it down to fit your own goals (like 10 short stories in 30 days or 30 flash fiction stories in 30 days), the NaNoWriMo experience will reward you for your efforts and remind you that writing is something that you want to do and can be fun! NaNoWriMo is like the Carnival of writing and I hope to see you there this year!
