Without ambition one starts nothing. Without work one finishes nothing. The prize will not be sent to you. You have to win it. The manwho knows how will always have a job. The man who also knows why will always be his boss. As to methods there may be a million andthen some, but principles are few. The man who grasps principles can successfully select his own methods. The man who tries methods,ignoring principles, is sure to have trouble.
