The interesting thing about this book is the way you need to change your mind in order to have financial freedom.Since childhood we are taught that we must study, go to school to have a profession or trade.But they don't teach you how to meet your needs in a simple and visionary way.That's what this book teaches, many people don't see it that way.But the reality is that the author put in a grain of knowledge about something that few people in the world already knew and have passed on to their descendants.
