The pattern

not what you say about your work — what your body does at six on a sunday.

it's free, it takes no time, and it's more accurate than most of the metrics people pay for.

comment AUDIT and i'll send you the free life audit — twelve questions, six minutes.

The mechanism behind it

Sunday evening is the most honest diagnostic I know.

Not what you say about your work — what your body does at six on a Sunday. If it has a texture, something in the week is unresolved and you've been outrunning it since Wednesday. If it doesn't, the design is holding.

Free, instant, and more accurate than most of the metrics people pay for.

The full list is unimpressive on purpose. White space in the week that you defended. Four hours unreachable. Nobody at home managing your mood. Finishing the day with something left. Not being the smartest person in your own company.

None of it photographs well. All of it is rare.
