Where to begin? I actually had fun reading this book, to be honest. It is, if nothing else, a bit inspirational and motivational. To the author's credit he has (and I have emphasized this before) come up with a catchy title and gimick to sell you a book--good for him. What's inside, though, are things that you can find better handled by other authors in other books.
In the first part of the book one can't help notice what a great guy the author is. We notice this becasuse he tells us. We are to believe that he has gone through the Hero's Journey and back again before his late 20's. Now, dear reader, he has distilled the fruits of his vast experience and wisdom into this little gem. Read it, and you will never have to work again. Just be sure to purchase with the 8 minute ab workout.
We get a lesson on the Pareto Principle. If you have never heard of the Pareto Priciple before (otherwise known as the 80/20 rule) you should go back to junior high. BTW, Brian Tracy has discussed this principle and its implications ad nauseum. The author would have us believe that he personally redicovered in some forgotton tome (probably while motorcycle kung-fu rock climbing in Bora Bora--between kendo lessons) and was just about the first to ever apply it to his life.
Later in the book we get some basic info (all easily found in more detail in other books) about starting a web business, outsourcing your workload, etc.
I can appreciate some of this as I had a web business for several years. This section of the book is an interesting read, but little more. If anything, maybe it will inspire someone else to get started on their own enterprise. And that's perfectly fine. If the author accomplishes this, then good. After all, I don't necessarily think that he's a bad guy, just a shameless self promoter and a bit of a charlatan.
Authors such as Ferriss are common: someone falls a** backwards into a relatively easy existence and then decides that they are experts and proceeds to seel their "secret" to success to everyone else--which helps them get REALLY successful. But here's the deal: One hit wonders are not experts. When you've started 4 or 5 businesses and grown each of them to the point where they are self sufficient, THEN you can call yourself an expert. Striking it lucky one time in stocks, real estate during a bubble, or starting one business do not constitute experience.
In the end, I think that the author does his readers a bit of a disservice by telling them that work is not necessary to be financially successful. I have known both success and failure. I have seen others go, literally, from rags to riches (and sometimes back again). Over the years I guess I have given this subject some thought. My conclusion is that you will not get there (wherever "there" may be for you) by working four hours per week. Vision, hard work, and persistence are the 3 main "secret" ingredients for success. Just as exercise and eating right are necessary to be in shape. But telling people this doesn't sell books.
P.S. Can't help noticing how many 5 star reviews there are for this book from people who have only written one review. Hmmm...
