This is one of my all-time favorites.
The Man in the Arena by Theodore Roosevelt
“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 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 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.”
