The credit belongs to the man who is actually in the arena, whose face is marred by dust, sweat, and blood, who knows the great enthusiasms, the great devotions, and spends himself in a worthy cause; who at best if he wins, knows the thrills of high achievements, and if he fails, at least fails while daring bravery; so that his place shall never be with those cold and timid souls who know neither victory nor defeat. Theodore Roosevelt
