Every great work of art has two faces, one toward its own time and one toward the future, toward eternity.

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

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

Your past is not your potential. In any hour you can choose to liberate the future.

The future enters into us, in order to transform itself in us, long before it happens.

Times and conditions change so rapidly that we must keep our aim constantly focused on the future.

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

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

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

With the past, I have nothing to do nor with the future. I live now.
