There are three things which the superior man guards against. In youth ... lust. When he is strong ... quarrelsomeness. When he is old ... covetousness.
ConfuciusListen much, keep silent when in doubt, and always take heed of the tongue; thou wilt make few mistakes. See much, beware of pitfalls, and always give heed to thy walk; thou wilt have little to rue. If thy words are seldom wrong, thy deeds leave little to rue, pay will follow.
Confucius
