When you jump for joy, beware that no one moves the ground from beneath your feet.

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

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

They must often change, who would be constant in happiness or wisdom.

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

No change of circumstances can repair a defect of character.

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

There is nothing permanent except change.

A heart well prepared for adversity in bad times hopes, and in good times fears for a change in fortune.

All things must change to something new, to something strange.
