It is not the critic who counts, nor the man who points out how the strong man stumbled 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 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 triumphs 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 know neither defeat nor victory.
Theodore Roosevelt at the Sorbonne, in Paris, France on 23 April, 1910
