If you want to keep something concealed from your enemy, don’t disclose it to your friend.

There are three types of friends: those like food without which you can’t live those like medicine which you need occasionally and those like an illness which you never want.

There are four types of men in this world: 1. The man who knows, and knows that he knows; he is wise, so consult him. 2. The man who knows, but doesn't know that he knows; help him not forget what he knows. 3. The man who knows not, and knows that he knows not; teach him. 4. Finally, there is the man who knows not but pretends that he knows; he is a fool, so avoid him.

Man is wise only while in search of wisdom; when he imagines he has attained it, he is a fool.

The first step in the acquisition of wisdom is silence, the second listening, the third memory, the fourth practice, the fifth teaching others.

A tiny fly can choke a big man.

Misfortune may become fortune through patience.

Worry over what has not occurred is a serious malady.

A wise man's question contains half the answer. Unfortunately the other 50% is harder to come by!

Faith is the summit of the Torah.
