There is no smarter professor than life, and no wiser sage than experience.

To be knowledgeable, sit before scholars; to be wise, sit before life.

Esteem intelligence, cherish knowledge, and value understanding, but trust wisdom.

Learn what you can, teach what you know, live how you ought.

Knowledge is the path, understanding is the way, wisdom is the highway, and enlightenment is the destination.

The most valuable things in your life are always the things that money cannot buy.
