“is not the critic who counts; not the man who points out where 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 with dust and sweat and blood. At best, he knows the triumph of high achievement; if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory or defeat.”
