"...It is not the critic who counts, not the man who points out where the strong stumbled, or how the doer could have done better. The credit belongs to the man who is in the arena, his face marred by dust and sweat and blood, who strives valiantly, who errs and falls short again and again: there is not effort without failure.

But he who tries, who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause, at best knows the triumph of achievement, and at the worst fails while daring. His place shall never be with those cold and timid souls who know neither victory nor defeat."

- Theodore Roosevelt
