It’s not the critic who counts. It’s not the man who points out where the grown man stumbles, or how the doer of deeds could have done them better. The credit belongs to the man who actually is in the arena, who strives violently, who errs and comes up short again and again, who knows the great enthusiasms, the great devotions, and spends himself in a worthy cause, who if he wins, knows the triumph of high achievement, but who if he fails, fails while daring greatly, so his place will never be with those cold and timid souls who know neither victory nor defeat.
—Theodore Roosevelt, 26th President of the United States
