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 them
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 comes short again and again; who knows the
great enthusiasms, the great devotions, and spends himself in a
worthy cause; who, at the best, knows in the end the triumph of high
achievement; and who at the worst, at least fails while daring
greatly, so that his place shall never be with those cold and timid
souls who know neither victory nor defeat.
