It is not the critic who counts, not the man who points out how the strong man
stumbled, or where the doer of deeds could have done better. The credit
belongs to the man who is actually in the arena; whose face is marred by the
dust and sweat and blood; who strives valiantly; who errs and comes short
again and again; who knows the great enthusiasms, the great devotions and
spends himself in a worthy cause; who at the best, knows in the end the
triumph of high achievement, and who, at worst, if he fails, at least fails
while daring greatly; so that his place shall never be with those cold and
timid souls who know neither victory or defeat..
