It is not the critic who counts, nor the man who points out where the strong man stumbled, or where a doer of deeds could have done them better. The credit belongs to the man in the arena whose face is marred by dust and sweat and blood, who strives valiantly, who errs, and who comes up short again and again, who knows the great enthusiasms, the great devotions, and spends himself in a worthy cause. The man who at best knows the triumph of high achievement and who at worst, if he fails, fails while daring greatly, so that his place will never be with those cold timid souls who never knew victory or defeat. Theodore Roosevelt
(26th President of the United States, 1858-1919)
