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 better. the credit belongs to the man who is actually in the arena, whos face is marred by dust and sweat and blood; who strives valiantly; who errs, and comes short again and again because there i no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms; the great devotions; who spends himself in a worthy cause; who at the best knows in the end 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 know neither victory nor defeat.
Theodore Roosevelt
