Getting to the 50,000 word marker is relatively easy if you've gotten things plotted out, you've gotten the characters lined up, and you avoid the pitfalls of painting yourself into corners that you didn't expect.
I'm hitting the 50,000 finish line a lot earlier than usual as well. Got a full week left of the NaNo campaign to get more of the bits and pieces I've got floating around here.
Next thing up is actually finishing the NOVEL ITSELF - something I haven't done in any previous effort. If I can focus on THAT...
Then I can worry about hiring somebody for the cover art. ;-)
