A well-made detail gives ease to people who never examine its construction.

Good work usually hides itself. A handle at the right height, a step with an edge you can see, a door that closes without a shove: none of it draws attention, and that is the point. The people helped most are rarely the ones who could name what helped them. Ease is the evidence, and it looks like nothing having happened.

Pick something you have made or maintain and ask who moves through it without thinking. Then improve a detail nobody will thank you for. Small ease, widely spread, is worth more than a feature people applaud.
