This goal has the following fine print specified by mad:
this is for my work inbox so i can't derail on days i'm not in the office (that includes the weekend) - if i derail on one of these days then it's not legit and the beeminder peons shall have to reset my graph.
that said, i should be making safety buffer to weather weekends and working from home days. but i don't have to.
if i had such a busy day at work that i couldn't delete or file ~30 emails then i guess i'm off the hook too
