Getting to 50,000 words is one thing.
For starters, you badge up. :)
But the novel itself is - even at 50,000+ words - halfway through. I haven't even gotten to the breaking point for one of the main characters, and the climactic battle not yet in sight. The month of December is gonna be both a continuing writing frenzy and a push to get the first draft (oh Lord is it rough) cleaned up for any half-decent publishing attempt.
The best thing is that there's a sense of accomplishment here. Just gotta get past the next hurdle is all...
