The credit belongs to the man who is actually in the arena; whose face is marred by dirt and sweat and blood; who strives valiantly, who errs and comes short again and again; who knows the great enthusiasms and spends himself in a worthy cause;
who, at the best knows in the end the triumph of his 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 know neither victory or defeat.

-Theodore Roosevelt
