The inevitable weakness of metrics

There are plenty of useful things a metric can reveal. There are even more it can obscure or corrupt. After more than a decade of tracking my life in growing detail, I came to see that the promise of numbers—to bring order to health, work, and daily life—wasn’t delivering what I had hoped.

My early aim was not productivity so much as self‑knowledge, a desire for clarity that, in retrospect, proved to be my first mistake. My first tool was a small, plastic clip‑on Fitbit that counted steps. That simple score soon mutated: six thousand steps became ten, then fifteen, then twenty thousand.

Pedometers gave way to heart‑rate monitors, smartwatches, sleep‑tracking rings, and macronutrient apps, while web analytics offered page views, followers, and engagement as proxies for job success. Metrics quietly reshaped what I considered important. Two lessons stood out.
