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 and comes up short again and again; who knows the great enthusiasms, the great devotions, and 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 daring greatly.
– Theodore Roosevelt Great Quotes from Great Leaders, 127
