More quotes by Theodore Roosevelt

"The only man who never makes mistakes is the man who never does anything."
"The things that will destroy America are prosperity-at-any-price, peace-at-any-price, safety-first instead of duty-first, the love of soft living, and the get-rich-quick theory of life."
"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."
"Far and away the best prize that life has to offer is the chance to work hard at work worth doing."
"Believe you can and you're halfway there."
