A missed chance deserves a lesson small enough to remember under pressure.

Large conclusions drawn from disappointment rarely survive the next difficult moment. Under pressure nobody recalls a paragraph about their own character. They recall one short instruction, if they have one ready. What you take from a miss is only worth what you can hold in a hurried mind.

Take something recent that did not go your way and reduce it to a single sentence you could say to yourself in a doorway. Keep only what would change the next thirty seconds, and let the longer analysis go.
