The man who starts out simply with the idea of getting rich won’t succeed; you must have a larger ambition. There is no mystery in business success… If you do each day’s task successfully, and stay faithfully within these natural operations of commercial laws which I talk so much about, and keep your head clear, you will come out all right. – John D. Rockefeller
