I'm making progress if today's problems are different from yesterday's.

A man's accomplishments in life are the cumulative effect of his attention to detail.

The United States of America does not have friends; it has interests.

Peace will never be won if men reserve for war their greatest efforts, Peace, too, requires well-directed and sustained sacrificial endeavor. Given that, we can, I believe, achieve the great goal of our foreign policy, that of enabling our people to enjoy in peace the blessings of liberty.

Mankind will never win lasting peace so long as men use their full resources only in tasks of war. While we are yet at peace, let us mobilize the potentialities, particularly the moral and spiritual potentialities, which we usually reserve for war.

The world will never have lasting peace so long as men reserve for war the finest human qualities. Peace, no less than war, requires idealism and self-sacrifice and a righteous and dynamic faith.

The measure of success is not whether you have a tough problem to deal with, but whether it is the same problem you had last year.
