Overthinking a mistake replays it a thousand times. Fixing it takes one. Do the one.

Replaying a mistake feels like responsibility and does none of the work. Each repetition reinstalls the discomfort without changing anything in the world, which is how you can spend a week on it and end up exactly where you started. The repair is usually one short action: a message, an apology, a corrected submission. Thinking is cheap and endless, and doing is what ends it.

Name the single action that would actually address the thing you keep turning over. Send it, say it or redo it today, even badly. The replaying tends to stop on its own once the real step has been taken.
