A big part of this book is inspired by the teachings of Mr. Charles Francis Haanel, who in the year 1912 wrote a marvelous book that is now in the public domain.  
The book I am referring to is called “The Master Key System” and is a book in which we can see from different points of  view how it depends on us, on our Thoughts and on the right  application of these thoughts, to accomplish and obtain from  our lives, exactly what we wish for.
