a solid education in low self worth plays out in observer bias. Wandering around prone to see where you've fucked up/haven't done enough is a pretty good guarantee that you will spot it, and promptly beat yourself up for it, which like most censure doesn't really improve anything.
Also, with the exception of some pickles and a muffin, I haven't eaten anything since 1:30 yesterday. I think this is my cue to grab a shower and walk some, see if I can make it to the nearest place open later.
