*thwacks muses on their collective noses with rolled-up newspaper*

I know exactly what you mean about that frustration. This is exactly why I tend not to write for challenges, fic exchanges, gift ficlets, etc.: my muses are anything but disciplined. And I don't think this is a problem limited to me; I'm certain that the official muse beverage is absinthe, and that they have a personality that would make them right at home with that crowd.

PS - Congrats on finishing NaNo. I am officially impressed by anyone who writes so much in such a short span.
