How can I study from below, that which is above?

A man may learn wisdom even from a foe.

To win the people, always cook them some savoury that pleases them.

Shall I crack any of those old jokes, master, At which the audience never fail to laugh?

The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers.

If you strike upon a thought that baffles you, break off from that entanglement and try another, so shall your wits be fresh to start again.
