There are three friendships which are advantageous, and three which are injurious. Friendship with the upright; friendship with the sincere; and friendship with the man of much observation: these are advantageous. Friendship with the man of specious airs; friendship with the insinuatingly soft; and friendship with the glib-tongued: these are injurious.
The superior man does what is proper to the station in which he is; he does not desire to go beyond this. In a position of wealth and honor, he does what is proper to a position of wealth and honor. In a poor and low position, he does what is proper to a poor and low position.
These are the four abuses: desire to succeed in order to make oneself famous; taking credit for the labors of others; refusal to correct one's errors despite advice; refusal to change one's ideas despite warnings.
If a man is respectful he will not be treated with insolence. If he is tolerant he will win the multitude. If he is trustworthy in word his fellow men will entrust him with responsibility. If he is quick he will achieve results.
The superior man honors his virtuous nature, and maintains constant inquiry and study, seeking to carry it out to its breadth and greatness, so as to omit none of the more exquisite and minute points which it embraces, and to raise it to its greatest height and brilliancy.
