A shrewd enemy will teach you more than a foolish friend.

Ignore those who resent you. Avoid those who begrudge you. Excuse those who envy you. Pity those who hate you.

Love fights with a kiss; hate fights with a fist.

Love your haters, but don’t waste time trying to appease them.

You meet many wolves in sheep’s clothing;you are prey until they find outyou have the heart of a lion.You meet many snakes in the grass;you are in danger until you burnthe plain in which they hide. Worse than a hostile enemyis an accomplished, secret one.Worse than a foolish superioris an impenitent, arrogant one. Worse than a sage's rebuke is life's chastisement.

Use intelligence for your opponents,shrewdness for your enemies,commonsense for your acquaintances,and resourcefulness for your friends.When your opponents are making a mistake, do not disturb them.When your enemies are making an error, do not caution them.When your allies are making a mistake, restrain them.

If you have no enemies, you are of no significance.If you have great enemies, you are of great significance.If you have extraordinary enemies, you are of extraordinary significance.

When God is on your side, He uses the plots of your enemies to advance your cause.

Learn from acquaintances, and you are clever; from friends, and you are intelligent; from enemies, and you are shrewd; but learn from all, and you are wise.
