No, that wordcount is not a mistake. Today was what is known in the writing world as a GOOD day. I've hit 100 pages. Not bad. And it means that I've reached my goal for the month, so even if writing is scarce next week due to travel etc, anything from this point in is gravy.
It's hard to remember when you're having the unflow-y, tooth pulling times, that there are days like this when the words come. But sometimes you just have to hang in there until they do.
