I think that this is yet another “fishing” book to fish innocent readers by a fancy book title.

I picked up this book because I saw a Korean version of this book and found one in English in the library. To my disappointment, this book does not convey “useful” information. As the author put it, he basically borrowed many concepts from already existing concepts created by others. What is new in the book is the ego of the author on how he made a fortune on a business, then ruined the business, and came back with another fortune in another business.

After finishing his book, I feel that he is trying to make yet another fortune out of this book.
