Well, nuts. Last night my goal was to cross the 40,000 word threshold, but I just missed it. I was tired, and I was at the end of the chapter, and I didn’t want to force myself through those last 400 words.
However! This morning I wrote very well and got over the line, though I didn’t actually check my wordcount yet. And I finally got my characters into a long-awaited secret chamber, though the lovebirds have started fighting and things will generally be downhill from here.

Sometimes, finishing just before your day goal is a good thing – there’s the mounting anticipation & motivation to really get into it the next day. Best wishes to the finish line.
