4.0

Personally, Robert Kiyosaki is one of my favorite person in the field of finance and business. And he is my teacher of The Cashflow quadrant and at the very beginning I've learned about balance sheet and Cashflow from Robert Kiyosaki.
The Business School, this book is normally based on the "Networking" and "Network Marketing." But he didn't went through a detailed discussion in this book. Frankly, I've learned many things from this book but a little about network marketing from this book. Robert just introduced the reader with "Network Marketing" in this book. And tried to make us understanding the value and future possibilities of this Business field.
But overall, the book is good. But not close to the "Rich dad poor dad" from anywhere.
