Things I have done to prep:
collected 150 pages of folklore and anthropological tidbits that are related to my story so I won't spend endless hours searching the internet for this when I should be writing -- Check!
Updated my monster list of names (and I mean monster...something like 346 pages in my word processor) to keep me off the net looking for just the right name while I'm writing -- Check!
Added Led Zeppelin's Mothership to my playlist of things to listen to -- Check!
Added a bunch of Nanowrimo buddies so I can't slip beneath the radar -- Check!
Downloaded and installed Storybook to help me keep track of things -- Check!
Have a place to work offline when temptation not to write gets too much -- Check! (and thank goodness for flash drives)
Named leading characters and important locations to keep from time sink problems later on -- In Process, sort of Check
Finished plot outline (er...worked on it, but not quite checked)
Finally got Pink to agree to focus on one story -- Check! (she better! Or I take away her champagne and truffles and give her watered sake and leftover popcorn)
Wow...a lot more together than I usually go into these things...I must really wanna finish this time! LOL.
Now, back to the making notes salt mines...
