Don't waste your money on this book. It may, indeed, have some insights in it somewhere, but I didn't find any before getting bored of wading through the shameless padding interspersed with comments linking whatever platitude he'd just trotted out with your career. I got the feeling that this book is simply an attempt at making money by ticking boxes: will the reader read all the way through in the hope of improving his income? Does it lay the blame on somebody apart from the reader?It reminded me of undergraduate essays written by students who would attempt to meet word-counts by setting themselves minimums on each element of their work, irrespective of the element's importance.Last point: if it's really written by a psychologist, shouldn't there be, well, references to peer-reviewed studies? This appears to be a collection of waffle that somebody thought up on their own.
