I've observed that, throughout our industry, these areas have been and continue to be developed by individuals who, for whatever reason, have become successful. These are the people who have gotten there. In their desire to help others get there, the leading marketers then outline what they did on their journey to success as The Way to get there. And these are translated into systems, functions, techniques, procedures and tools.
What's most interesting to me, as I've studied and worked to understand this area, is my observation that there's a huge piece missing between the way these elements were developed, and the way they are taught. What I mean is, the development of any of these elements was based on a particular individual's result, which was based upon his or her circumstance, situation, desires, needs, etc. Then what gets taught is that Style & Technique, rather than the concept of what they did. What we are after here is the concept and the mechanics of this area.
