A man's usefulness depends on his living up to his ideals insofar as he can. It is hard to fail but it is worse never to have tried to succeed. All daring and courage, all iron endurance of misfortune, make for a finer, nobler type of manhood. Only those are fit to live who do not fear to die; and none are fit to die who have shrunk from the joy of life and the duty of life.
Theodore RooseveltAnd it is through strife and the readiness for strife that a man or a nation must win greatness. So, let the world know that we are here and willing to pour out our blood, our treasure, our tears. And that America is ready and if need be desirous of battle
