How much do I want to read more? 5/10

The "four" are responsible for transforming the life of billions of people, they have generated unprecedented wealth ($2.3 trillion).
Those 2 facts are the plain manifestation of Zig Ziglar motto: “You will get all you want in life, if you help enough other people get what they want.”
I only overlook the book, and my feeling is it's not worth reading carefully from A to Z, I actually doubt there's much to learn in this book.
