The best way to reach a high income seems to be publishing bad books without any substantial content.

This book is nowhere close to fullfiling the promises it makes on the back-cover (see synopsis). In fact, it is even from time to time incoherent and the so called "sage" advice is so superficial that a nine-year old could have come up with it. Granted, some of the short anecdotes are worth remembering, but they don't justify buying the book.

Buy something else, as this wont help you in any way.
