Burning the headless chickens at both ends.

There's something in the 4 degree air here that is making it tough to focus and work. I had a guy yesterday explain it like this: when you are walking through snow and ice for weeks at a time, unsure of your footing, it makes your heart and mind unsure of itself. And he might have nailed it.
It's draining to always be jumpy. It keeps your breathing constrained to to the upper limits of your lungs. It steals your focus. You are tired and behind. And the work just keeps on coming.
Add to that the occasional all niter, an uneven diet, and a naturally restless soul, and it could be trouble. I'm trying to keep things checked, but no promises.
