It is not the critic who counts, nor the man who points out how the strong man stumbles, 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, because there is no effort without error or shortcoming; who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause; who, at the best, knows in the end the triumph of high achievement, and who, at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who knows neither victory nor defeat
PRESIDENT THEODORE ROOSEVELT
