There are two primary choices in life: to accept conditions as they exist, or accept the responsibility for changing them.

Intelligence is the ability to adapt to change.

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

You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.

The most important knowledge is that which guides the way you lead your life.

If you want to be happy, be.

Education is the most powerful weapon which you can use to change the world.

Those who cannot change their minds cannot change anything.

No matter what people tell you, words and ideas can change the world.
