A great nation is like a great man:When he makes a mistake, he realizes it.Having realized it, he admits it.Having admitted it, he corrects it.He considers those who point out his faultsas his most benevolent teachers.He thinks of his enemyas the shadow that he himself casts.
LaoziThere is no calamity greater than lavish desires. There is no greater guilt than discontent. And there is no greater disaster than greed.
Laozi
