The small adjustment that works deserves understanding before becoming routine.

When a change fixes something, the temptation is to keep doing it and move on. Without knowing why it worked, you cannot tell whether it will keep working, whether it was the change at all, or which part of it mattered. A routine built on an unexamined success is fragile in a way that is hard to notice until it fails.

The next time something improves, spend five minutes on what you think caused it. Even a rough answer gives you something to adjust when conditions change, instead of a habit you no longer understand.
