The Destiny book lacks purpose. Maybe except to benefit the author. The book is an aggregate of ideas and examples pulled from other sources. Most of them are good and relevant but deserve to be discussed in a context. The book feels like a collection of notes written through the years and put into a book without connections between them.
This book is a good example of a "popular writer" issue. An author gets popular with one book and then starts producing many books after to milk their fame. Unfortunately fresh and interesting content is hard to produce and takes a lot of time. As a result any subsequent publishing is mediocre at best. My advice, be wary of authors with more than 1 book per decade.
I would not recommend this book to anybody.
