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 himself in a worthy cause; who at the best
knows in the end that triumph of high 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 soul who neither know victory nor defeat."
