But Bobby never permitted himself to worry needlessly. He was not one of those who with the least difficulty plunge into unnecessary discouragement and lose their capacity for action. It was not in his nature to waste his time and opportunities and energies worrying about what might happen, but what in the end rarely did happen. He conserved his mental and physical powers, and turned his mind and muscles into vigorous and practical action. And like every fortunate possessor of this valuable faculty, Bobby more often than not raised success out of failure.
