To amplify from the other side of the world:

善為士者，不武；善戰者，不怒；善勝敵者，不與；善用人者，為之下。是謂不爭之德，是謂用人之力，是謂配天古之極。 —老子

A good scholar is not a warrior; A good fighter is not angry; Those who are good at defeating enemies will not compete with them; Those who make good use of people are inferior. It is called the virtue of not competing, the power of using people, and the extreme of matching heaven and ancient times. —Laozi
