"The greatest merit is the man who is in the arena, face stained with dust, sweat and blood ... who knows the great enthusiasm, the great devotions; What sacrifices himself for a worthy cause, and if anything, try in the end the triumph of high achievement; And. .. if he fails, at least failed to dare great things. And therefore, his place may never be taken for those cold and timid souls who know neither wins or not Loss "
John F. Kennedy
