Classical Chinese · 道德經 (王弼本)
知人者智，自知者明。勝人者有力，自勝者強。知足者富。強行者有志。不失其所者久。死而不亡者壽。
English · James Legge
He who knows other men is discerning; he who knows himself is intelligent. He who overcomes others is strong; he who overcomes himself is mighty. He who is satisfied with his lot is rich; he who goes on acting with energy has a (firm) will. He who does not fail in the requirements of his position, continues long; he who dies and yet does not perish, has longevity.
