The first principle is that you must not fool yourself – and you are the easiest person to fool.
Richard Feynman, Caltech commencement address, 1974
Awesome quote by Roosevelt, “Daring Greatly…”
“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”
― Theodore Roosevelt
Never lose your hunger for new knowledge and new experiences.”
“A man may die, nations may rise and fall, but an idea lives on. Ideas have endurance without death.
[Remarks Recorded for the Opening of a USIA Transmitter, February 8 1963]”
― John F. Kennedy
