You can open the book at any point and learn something, or not learn something. He lets us walk into a fresh and empty room that has beautiful flowers and a window. Either focal point provides energy. If you want to understand why these times call for new ways of thinking, read this book. I love the paradigm-shift Mr. Nadler and Mr. Hibino put forward.
Every problem is unique.
Don't copy a solution from elsewhere. This is key to their methodology. Always and continually ask the purpose of solving the problem and the purpose of that purpose. Build in ways to monitor how the solution works and improve it over time. Read this book for the history.
