Small improvements compound when the same process runs thousands of times.

A change that saves thirty seconds is nothing once and substantial across a thousand runs. That arithmetic is why the most valuable improvements are often the least impressive to describe, and why fixing the small annoyance in a frequent process beats a dramatic one-off effort that touches something you do twice a year.

Look for the thing you do most often and find the friction in it that you have stopped noticing because you have adapted to it. Fix that one. The satisfaction is low and the return is high, which is roughly the opposite of how attention usually gets allocated.
