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

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

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

Change alone is eternal, perpetual, immortal.

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

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

If you don't like something, change it. If you can't change it, change your attitude.

Just because everything is different doesn't mean anything has changed.

You are always free to change your mind and choose a different future, or a different past.

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