Critics are worth absolutely nothing: all they do is point an accusing finger at the moment the strong suffer a defeat, or when they commit a mistake. True credit goes to those who are in the arena, their faces covered in dust and sweat and blood, fighting on bravely.
True credit goes to the one who makes mistakes, who fails but little by little gets things right, because there is no effort without mistake. He knows great enthusiasm and deep devotion, and spends his energy on something worthwhile. That is the true man, who in the best of hypotheses will know victory and conquest, and in the worst of hypotheses will fall, yet even in his fall he is great, because he has lived with courage and stands above those small-minded souls who will never know victory or defeat.
- Theodore Roosevelt
