NaNoWriMo - I signed up ×gulp×

Well, I've decided to try to do NaNoWriMo. I suppose I ought to come up with something new for it, but I don't have any ideas right now. I am working on a sci-fi novel, but that's been long going, and also in the wrong language. I hope I won't be stumped, and totally fail at even having an idea for it.

 

Anyone else doing it this year? I saw some people mention it last year, and that gave me the push to sign up.
