Change is the law of life. And those who look only to the past or present are certain to miss the future.

True happiness is... to enjoy the present, without anxious dependence upon the future.

Planning is bringing the future into the present so that you can do something about it now.

We are made wise not by the recollection of our past, but by the responsibility for our future.

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.

Change your life today. Don't gamble on the future, act now, without delay.

The only thing we know about the future is that it will be different.

The future... seems to me no unified dream but a mince pie, long in the baking, never quite done.

The past is really almost as much a work of the imagination as the future.

Some of the best lessons we ever learn are learned from past mistakes. The error of the past is the wisdom and success of the future.
