National Novel Writing Month

So I've decided that I'm likely to try my hand at NaNoWriMo this year. I've got my account set up, so I'll be set to start writing next month. I've got a few ideas floating around in my head. I just need to nail it down to something between now and then. It'll be something Superhero related since that is where most of my recent passion has been focused. I doubt I'll be able to hit the 50,000 word mark by the end of November, but I'll give it a try. What's the worst that can happen? I fail miserably and get nothing written. Like usual.
