Zigong said: “The errors of a leader are like an eclipse of the sun or the moon. When he makes an error, everyone notices; when he corrects his error everyone looks up to him in admiration.”
A leader doesn’t make many mistakes. But on the rare occasions he screws up, he doesn’t attempt to hide them so that everyone can see he deals with them.
Once the lesson is complete, he moves on sure in the knowledge that he will not make the same mistake again and that others have learned from his experience.
