This book took six years to write。

The material for those six years was drawn from twenty years of research and direct experience。

As a consequence， it represents a lot of information and crosses a very broad range of topics-systems theory， complexity， psychology， pain mindset， and more。 Rather than obey the standard industry practice of turning a blog article into a book， we have instead compressed several books into one comprehensive resource。 This means that you probably don't want to sit down and read it cover to cover。 This isn't Hary Potter。

Use this book as a textbook。 Study the portions that are most important to you right now， take notes and scribble all over it， and work to gradually expand your base of knowledge from isolated pieces to a complete system。
