A bad reputation takes one weekend to earn and a hundred ordinary good days to rewrite. Start stacking days.

Reputations run on an asymmetry: they collapse quickly and rebuild slowly, because one dramatic event carries more information for observers than a hundred ordinary ones. That is unfair, and it is also how attention works. Repair is genuinely available to you. It simply runs on a slower clock than the damage did.

Stop trying to explain your way out and start accumulating plain, unremarkable days of being reliable. Do not ask for the account to be settled early. People revise their view gradually, usually without ever mentioning that they did.
