Started doing some minor exercise (stretches, jumping jacks, a few pushups and crunches) in the morning and at lunch. Low effort, yet better than being completely sedentary all day.

Listening to upbeat music at work to stave off creeping negativity. Has the unfortunate side effect of making me fidget-dance.

In the past few days there's been at least three separate occasions when I was rationalizing, noticed I was rationalizing, and then, rather than change my behavior, proceeding to rationalize why it was okay for me to rationalize. I discovered I'm not nearly as determined to be rational as I say I am.
