The person who treats your error as ordinary has reduced the cost of trying again.

Reactions to a mistake set the price of the next attempt. Someone who takes your error calmly, corrects it, and moves on has quietly told you that the world does not end here, and the next thing you try becomes cheaper to attempt. A big reaction does the opposite, and the caution it creates lasts far longer than the incident did.

When somebody gets something wrong near you, keep your face and your voice ordinary. Fix what needs fixing without commentary about the person. It is one of the few things you can do in five seconds that changes how brave someone is willing to be.
