John F. Kennedy Quote
But Goethe tells us in his greatest poem that Faust lost the liberty of his soul when he said to the passing moment: "Stay, thou art so fair." And our liberty, too, is endangered if we pause for the passing moment, if we rest on our achievements, if we resist the pace of progress. For time and the world do not stand still. Change is the law of life. And those who look only to the past or the present are certain to miss the future.
