Bench marks for a good day

A benchmark is an incredibly useful thing. 

Surveyors use them to measure elevation.

I use them as a way to measure my relative failure or success.  Lately in the library I've developed a few new ones.  For example, any day when the police don't come and there are no bodily fluids on the floor or furnishings is a good day.  It's incredibly easy to have a good day when you're keeping it all in perspective.  It just depends on where you put your bench marks.
