Confucius said, “The noble person has three things to guard against: in youth, when one’s vital energies (xue qi) are not yet settled, guard against lust; in prime adulthood, when vital energies are at their strongest and most vigorous, guard against contentiousness; in old age, when vital energies have declined, guard against greed.”
Confucius said, “When serving a noble person, there are three common faults: to speak before it is your turn is called impetuousness; to remain silent when it is your turn to speak is called concealment; and to speak without observing the other’s expression is called blindness.”
Confucius said, “There are three kinds of beneficial friends and three kinds of harmful friends. Friendship with the upright, friendship with the trustworthy, and friendship with the well-informed – these are beneficial. Friendship with the fawning, friendship with the insincerely agreeable, and friendship with the glibly eloquent – these are harmful.”
The Master said, “In language, it is enough that words convey meaning clearly.”
