Bill Cosby on wisdom

Always end the name of your child with a vowel, so that when you yell the name will carry.

In order to succeed, your desire for success should be greater than your fear of failure.

You can turn painful situations around through laughter. If you can find humor in anything, even poverty, you can survive it.

The only true wisdom is in knowing you know nothing.

Socrates470–399 BC

By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.

Confucius551–479 BC

True wisdom comes to each of us when we realize how little we
understand about life, ourselves, and the world around us.
