I made the mistake of buying this book without consulting the opinions of readers before, so I was disappointed. Indeed, there are only the sales pitch without real substance, with too heavy a use of the word "con". I think this book is suitable for people who need to vent themselves as living in a similar world, but if you want a book that contains something usable, effective, authentic, it n ' is not for you. Furthermore the author is hiding behind a false name, allowing it to attract the pigeons (or stupid if you prefer) without blemish to his real name, thus actually make a noise thanks to the use of the word "con", and anonymity that works pretty well in marketing (see the book without name).
