“It is not the critic who counts; not the wo/man who points out how the strong woman or man stumbles, or where the doer of deeds could have done them better.
The credit belongs to the woman or man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends herself or himself in a worthy cause;
who at the best knows in the end the triumph of high achievement, and who at the worst, if she or he fails, at least fails while daring greatly,
so that her or his place shall never be with those cold and timid souls who neither know victory nor defeat.”
– Theodore Roosevelt, A Citizen in the Republic Speech | Paris, 1910 (full speech here)
