Personally, I liked this book in which one feels the authentic person and full of common sense what the author of this book. We are entitled however to ask whether his method really works, the fact is that trying his method will not lead you to ruin and that the author of the book did not draw great benefit: it is not even she who has the online sales sites it refers in his work. The only aspect of the book that could be annoying for some is like repeating it throughout his book the various "pillars" of his method (cited above) - the advantage is that in the end it will back even in the toughest heads !!! -.
