It is not the critic who counts- not the man who points out how the strong man stumbled, or where the doer of deeds could have done 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 who comes short again and again. It is he who knows the great enthusiasm, the great devotions, and spends himself in a worthy cause; who at best knows in the end the triumphs of high achievement; and who, at worst, if he fails, at least fails while daring greatly so that his place shall never be with those cold timid souls who know neither defeat nor victory.
~ Teddy Roosevelt
