Aim for one-percent improvement

Target a tiny, repeatable gain rather than a dramatic overhaul.

Why it works

A one-percent gain is small enough to be sustainable and frequent, and small frequent gains compound: repeated tiny improvements accumulate into large change over time, the way compound interest dwarfs a single deposit. Aiming low per rep is what makes the high cumulative total possible.

How to do it

1. Ask what the smallest meaningful improvement on today’s version would be.
2. Make that improvement, then bank it as the new baseline.
3. Repeat — the gain is in the accumulation, not any single rep.

Evidence

The compounding logic is mathematically sound and consistent with how consistency outperforms intensity in habit research; "one percent" itself is an illustrative figure, not a measured rate of human improvement. (mechanistic)

Real progress is rarely a smooth 1% per day; the figure is a motivating heuristic for the value of small, steady gains.

Common mistake

Treating one-percent as too trivial to bother with, and reaching for a dramatic change that does not stick — losing the compounding entirely.
