The critic and the doer

It is not the critic who counts; not the one who points out how the strong person stumbles, or where the doer of deeds could have done them better. The credit belongs to the person who is actually in the arena, whose face is marred by the dust and sweat and blood; who strives valiantly; who errs, and 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 the great enthusiasms, the great devotions; who spends himself or herself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he or she fails, at least fails while daring greatly, so that his or her place shall never be with those cold and timid souls who know neither victory nor defeat.
