Well, it has for me anyway. I managed to get 14000 words done - which isn't that bad I guess - but the demands of the movie made me feel guilty every time I tried to write something.
Curses that the very last and most fretful part of making the movie coincided with NaNoWriMo.
Having said that, I hope I'm going to write my novel properly once the dust has settled, because I think I had something fun going on. I enjoyed it anyway!
Hey ho. Here's to the next year! And I might plan it out better next time too.
