Hi Sidneiye,
I haven't read "The Master Key System" (or even heard of it until now).... But if you haven't read the book, and you'd like to, you can find it online for free here....

(The book is now in the public domain.)
As that web page says....
Rumor has it that while he was attending Harvard University, Bill Gates discovered and read The Master Key System. It was this book that inspired Bill Gates to drop out of the University and pursue his dream of "a computer on every desktop."
Of course, it's just a rumor... Or is it? :)
Or how about this?
It is Silicon Valley's secret that almost every entrepreneur who made a fortune in recent years did so by studying the words Mr. Haanel penned over eighty years ago! Almost every millionaire and billionaire in the Valley read The Master Key System by Charles F. Haanel. Since this book was no longer in print until recently, copies of The Master Key System became a hot commodity in the Valley.
According to what I've read elsewhere, Charles Haanel was a very successful entrepreneur BEFORE he wrote "The Master Key System"....
Hmmm.... Sounds like it could be worth a look. :)
