It is not the critic who counts; not the man who points out how the
strong man stumbles, or where the doer of deeds could have done
them better. The credit belongs to the man who is actually in the arena,
whose face is marred by dust and sweat and blood; who strives valiant-
ly; who errs, who comes short again and again, because there is no ef-
fort 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 the
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 souls who neither know victory nor defeat.
- Theodore Roosevelt
