"In order to be a success in business, there is one thing you must do. You cannot be successful without it. That is WORK. I have not told you anything new. Everyone knows that you cannot be successful in anything without work. Why does not everyone work? Because some lack the one thing that makes men want to work - ENTHUSIASM. That is something no one can give you. You must acquire it yourself, and the only way that you can become enthusiastic about anything is to have a thorough KNOWLEDGE of it. You have never seen an enthusiastic man who was lazy."
