The NaNoWriMo website offers great tips for getting started, finding support from fellow writers, and moving step-by-step through this enormous writing process. I know it may sound daunting, but there is no harm in trying it out. I have several awesome students who are taking on the challenge, and I can't wait to see what they will produce over the next month.
And even if you can't quite get to a novel-length product, do your best to do something creative this month. Whether it's a short story or two, a few poems, or something else, try getting some form of writing done during the month of November. Good luck!
