“Life means change; where there is no change, death comes.”

“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. Both life and death are parts of the same Great Adventure.”

“I stand for the square deal," Roosevelt said. "But when I say that I am for the square deal, I mean not merely that I stand for fair play under the present rules of the game, but that I stand for having those rules changed so as to work for a more substantial equality of opportunity and of reward for equally good service. One word of warning, which, I think, is hardly necessary in Kansas. When I say I want a square deal for the poor man, I do not mean that I want a square deal for the man who remains poor because he has not got the energy to work for himself. If a man who has had a chance will not make good, then he has got to quit.”

“Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty… I have never in my life envied a human being who led an easy life. I have envied a great many people who led difficult lives and led them well.”

“In order to succeed we need leaders of inspired idealism, leaders to whom are granted great visions, who dream greatly and strive to make their dreams come true; who can kindle the people with the fire from their own burning souls. The leader for the time being, whoever he may be, is but an instrument, to be used until broken and then to be cast aside; and if he is worth his salt he will care no more when he is broken than a soldier cares when he is sent where his life is forfeit in order that the victory may be won.”

“I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of effort, labor and strife; to preach that highest form of success which comes, not the the man who desires mere easy peace, but to the man who does not shrink from danger, from hardship, or from bitter toil, and who out of these wins the splendid ultimate triumph.”

“There is a delight in the hardy life of the open.There are no words that can tell the hidden spirit of the wilderness, that can reveal its mystery, its melancholy and its charm.The nation behaves well if it treats the natural resources as assets which it must turn over to the next generation increased; and not impaired in value.Conservation means development as much as it does protection.”
