Never mistake knowledge for wisdom. One helps you make a living; the other helps you make a life.

The wise man can pick up a grain of sand and envision a whole universe. But the stupid man will just lay down on some seaweed and roll around in it until he's completely draped in it. Then he'll stand up and go, 'Hey, I'm Vine Man.'

If you can't say anything - don't.

A fool sees not the same tree that a wise man sees.

He dares to be a fool, and that is the first step in the direction of wisdom.

No one is wise at all times.

The beginning of wisdom is the definition of terms.

Swallow what's bitter in the cup and move on.

The art of being wise is the art of knowing what to overlook.

If one extends knowledge to the utmost, one will have wisdom. Having wisdom, one can then make choices.
