The petty man is eager to make boasts, yet desires that others should believe in him. He enthusiastically engages in deception, yet wants others to have affection for him. He conducts himself like an animal, yet wants others to think well of him.

There are successful scholars, public-spirited scholars, upright scholars, cautious scholars, and those who are merely petty men.

You look upon the seasons with expectation and await them: wy not seize the seasonal opportunities and exploit them?
