You must be the change you wish to see in the world.

Because things are the way they are, things will not stay the way they are.

There are three constants in life... change, choice and principles.

If you change the way you look at things, the things you look at change.

Change will never happen when people lack the ability and courage to see themselves for who they are.

No change of circumstances can repair a defect of character.

Be content with what you are, and wish not change nor dread your last day, nor long for it.

Change alone is eternal, perpetual, immortal.

One must change one's tactics every ten years if one wishes to maintain one's superiority.

Any change, even a change for the better, is always accompanied by drawbacks and discomforts.
