Ok, I have a plan for tomorrow. I've mentioned that my study seems to get unpleasantly warm unless I do some crazy stuff with fans and crank the AC down, while the library is cooler most of the time. So the plan is to move my desk and workstation into the library, as well as the TV and media PC, see how that works out temp wise. If things go as planned, then I'll move the art and knickknacks, and everything else, and turn the study into a storage/second library. Eventually when I get the new bookcases, I'll move the old ones in here, and put up the scifi/fantasy, and some of the other stuff I won't need right at hand, as well as just plain storage. It's going to be a pain to do (basically a mini move), but I think between the temp change and having more books around, and more room on the far wall for art will = a better lair vibe.
The plan is to wake up, eat, and start working while it's still relatively cool outside (and cool inside) and go from there. Assuming I sleep ok tonight, and wake up with some amount of vim and vigor. We'll see.
