The credit belongs to the man who is actually in the arena,
whose face is marred with sweat and dust and blood;
who strives valiantly: 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 triump of high achievement;
and who if he fails, at least fails while daring greatly,
so that his place shall never be with those cold timid souls who know neither victory or defeat.
Theodore Roosevelt
