I did it.
Today I was getting so close, I just pushed ahead and hit the 50,000 mark. The thing is, though, I'm only about 60% through my story. My intention now is to forge ahead and finish the darn thing. I've gotten into the habit of forcing out about 2,000 words every day. Even if I settle for less (which I feel I can, now that the pressure's off) I have every intention of finishing this story. Then I'll let it sit while I work on the one I put aside; when that's done, it'll go on "sit" while I come back to this one.
And the best part is that -- once it's all revised and polished and proofed; a process that's going to take considerably longer than a month -- I think I even have a place to submit it.
So come on, everyone; if I can do it, pretty much anyone can.
