When a man's knowledge is sufficient to attain, and his virtue is not sufficient to enable him to hold, whatever he may have gained, he will lose again.

To learn and from time to time to apply what one has learned - isn't that a pleasure?

As the water shapes itself to the vessel that contains it, so a wise man adapts himself to circumstances.

See a person's means ... Observe his motives. Examine that in which he rests. How can a person conceal his character?

Teachers open the door ... you enter by yourself.

Isn't it a pleasure to study and practice what you have learned?

Act with kindness but do not expect gratitude.
