The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

Be the change that you wish to see in the world.

Life would be tragic if it weren't funny.

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

Deciding what not to do is as important as deciding what to do.

Turn and face the strange.

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

Everyone thinks of changing the world, but no one thinks of changing himself.

Life is and will ever remain an equation incapable of solution, but it contains certain known factors.
