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

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

Change the changeable, accept the unchangeable, and remove yourself from the unacceptable.

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

All change is not growth, as all movement is not forward.

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

A fanatic is one who can't change his mind and won't change the subject.

Life belongs to the living, and he who lives must be prepared for changes.

If you want to change attitudes, start with a change in behavior.

Always remember that the future comes one day at a time.
