Life is like riding a bicycle. To keep your balance, you must keep moving.

Think good, and good follows. Think evil, and evil follows. You are what you think all day long.

It's not what you are that holds you back, it's what you think you are not.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

A clever person solves a problem. A wise person avoids it.

I have no special talents. I am only passionately curious.

When people talk, listen completely. Don't be thinking what you're going to say. Most people never listen.

Reality is merely an illusion.

Once we accept our limits, we go beyond them.
