The author pursues the practical thing than a theory. Economy is to study how to be rich in a short sentence. If so, the richest man in theory must be a professor in economics. However most professors do live comfortably, but they are not the richest person. Mr. Anthony Robinson said that if you want to be a best in a certain field find the best and copy him. While I study in the TCM School, I try to find a best acupuncturist. It had taken a year to find a true master to me. I bought his books and seminar materials and studied his books. There are a few information that I have not learned in the school. This idea makes me one of Korean 4 needle specialists. I could develop some unique… approaches that guarantee eczema treatment and acne to be healed within one month. If I don't treat within a month, I treat next month on me. If I still don't treat as promised, I will return the money paid. Is there any more practical way than this? The books I write would be practical one. Once anyone used it, so easy to follow.
