"If I wanted to become a tramp, I would seek information and advice from the most successful tramp I could find. If I wanted to become a failure, I would seek advice from men who have never succeeded. If I wanted to succeed in all things, I would look around me for those who are succeeding, and do as they have done." — Joseph Marshall Wade
