This year is my first NaNoWriMo. I was hoping to get to 50 000 and I passed it on the 19th November. I have a problem with finishing my novels-they start and then the characters face so many problems that I'm at fifty thousand already and have to finish up soon before I start abandoning it.
Another problem is that at about the 17th, I got about three good plots for next years NaNo stuck in my head. I like thinking up new plots and all, but that was rather annoying.
