More quotes by Theodore Roosevelt

"Comparison is the thief of joy."
"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."
"A man who has never gone to school may steal a freight car; but if he has a university education, he may steal the whole railroad."
"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."
"With self-discipline most anything is possible."
