A friend whom you have been gaining during your whole life, you ought not to be displeased with in a moment. A stone is many years becoming a ruby - take care that you do not destroy it in an instant against another stone.

A traveler without knowledge is a bird without wings.

A handsome woman is a jewel; a good woman is a treasure.

To the eye of enmity virtue appears the ugliest blemish.

Be sure, either that thou art stronger than thine enemy, or that thou hast a swifter pair of heels.

Reveal not every secret you have to a friend, for how can you tell but that friend may hereafter become and enemy. And bring not all mischief you are able to upon an enemy, for he may one day become your friend.

He who, when he hath the power, doeth not good, when he loses the means will suffer distress. There is not a more unfortunate wretch than the oppressor; for in the day of adversity nobody is his friend.
