[... re-acomodé un poco este discurso para tener una versión más amplia...]
'It is not the critic who counts; not the person who points out how the strong one stumbles, or where the doer of deeds could have done them better.
The credit belongs to the person 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/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/he fails, at least fails while daring greatly . . .'
