I'm sure part of the problem is that BHFT is being a headlong rush, all day long. By the time I get home, I'm tuckered out. I managed for the past two days to do some Pilates and cardio after work (because as "Zombieland" reminds us, one shouldn't wait until the Zombie Apocalypse to get in shape).
I have a week of vacation coming up. I look forward to some writing/comics time.
