Theodore Roosevelt actually said...

"Leadership is of avail only so far as there is wise and resolute public sentiment behind it."

"The life of duty, not the life of mere ease or mere pleasure—that is the kind of life which makes the great man as it makes the great nation."

"No man is warranted in feeling pride in the deeds of the army and navy of the past if he does not back up the army and the navy of the present."

"Their lives teach us to strive after in our own lives, not the thing which is merely pleasant, but the thing which it is our duty to do."
