Progress is impossible without change, and those who cannot change their minds cannot change anything.

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

Change alone is eternal, perpetual, immortal.

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

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

In order to change the world, you have to get your head together first.

For changes to be of any true value, they've got to be lasting and consistent.

To improve is to change to be perfect is to change often.

Sometimes if you want to see a change for the better, you have to take things into your own hands.

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