The mistake is done. The next choice, what you do in the next hour, is where people decide who you are.

After something goes wrong, attention usually goes backward, replaying and explaining. Everyone else is watching forward, at the hour immediately following, because that is the part that shows what you do with a bad situation. The mistake describes a moment; the response describes a person.

Give yourself a short window to feel it, then move to the first repairing action available. Tell whoever needs to know, fix what can be fixed today, and leave the analysis for when you are not in the middle of it.
