One thing I am doing, in theory, is writing a novel. I decided to try nanowrimo again this year, because I just don't have enough going on. If you aren't familiar with nanowrimo, it entails writing a 50,000 word novel(la) during the month of November, which boils down to 1667 words a day, which is not a lot of words to write in a day, but is a lot of words to write in the free time a normal person has on a typical day. I cheated by starting over the weekend, but I think this is reasonable since a 2000-word head start will hopefully keep me from getting discouraged the first time I have to stay at work past midnight (projected occurance: Wednesday) and therefore write zero words. As of now I've written 3,573 words, which means I'm just over 7% done. (Note there is no rule against the novel being really bad.)
Actually, I'm feeling pretty spiffy right now, because I have done most of the things I intended to do today, including going to the gym, writing my grandmother, and playing the piano. I've even had a nap! (much needed after attending, and getting semi-stuck in the subway on returning from, the Village Halloween parade) All of this is because I am no longer commuting to Princeton every day, which means I have an additional three hours daily to work, sleep, exercise, socialize, and keep the entropy-gremlins from taking over my apartment and/or life.
Now, I will close my computer - I've noticed it is a horrible time-suck at the end of the evening, when desultory perusal of facebook and various inexhaustible feeds seem much easier than going to bed - and battle the dust-bunnies, and then I will possibly get six full hours of sleep.
