Act with kindness but do not expect gratitude.

The Gods cannot help those who do not seize opportunities.

Love of goodness without love of learning degenerates into simple-mindedness. Love of knowledge without love of learning degenerates into utter lack of principle. Love of faithfulness without love of learning degenerates into injurious disregard of consequences. Love of uprightness without love of learning degenerates into harshness. Love of courage without love of learning degenerates into insubordination. Love of strong character without love of learning degenerates into mere recklessness.

There are those men who say to repay evil with kindness. But I say, how then are we to repay kindness? Repay kindness with kindness, but repay evil with justice.

You can cheat an honest man but not make a fool out of him.

Learn, as if never overtaking your object, and yet as if apprehensive of losing it.

In ancient times, those who wished to illuminate the world with virtue first brought order to their nations. Wishing to order well their nations, they first harmonized their families. Wishing to harmonize their families, they first cultivated themselves. Wishing to cultivate themselves, they first rectified their minds. Those who wished to rectify their minds first made their intentions sincere.
