It's hard to do both in the same month but I am trying very hard to do just that.
I'm about 8,000 words in to my writing for NaNoWriMo and I'm tempted to just scrap the whole thing and start again. I know that is the dumbest thing ever to consider doing but I really am. The story isn't going the way I thought it would go and there seems to be no getting it back on track.
