It's not the critic who counts, not the man who points out how a strong man stumbles, or where the doer of deed could have done them better. The credit belongs to the man who's 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 errors or shortcomings; but who actually strives to do the deeds, 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 by daring greatly, so that his place shall never be with those cold and timid souls who know neither victory nor defeat!

Theodore Roosevelt
