Vanity metrics vs. decisions: the filter test

Most dashboards are full of numbers that feel like progress but change nothing you do. One question sorts every metric into keep or delete.

Founders drown in metrics that flatter the ego and drive no action, while the two or three numbers that should govern spend get ignored. The filter test cuts through it: if a number can't change what you'd do this week, it's vanity. AI runs the test on your whole list and swaps each trap for its decision metric.
