There are a lot of disclaimers to be aware of, before you touch this book.
Firstly, this book has a particular target group in mind - business men and women, striving for success. A vast majority of examples that are brought up are set in the corporate world
Secondly, this book should be read at the right time, in the right place with the right mindset. It's not a book where you'll read a lot about studies, it's a book that's meant to change your view on the world by showing you where to look.

Now for the review per se, I have attended a workshop of Christian Busch and was thus aware of many of his examples and his reasoning. The book can be a little of a tough read, especially in the middle part, with many of the examples recurring and thus, redundant. Nonetheless, the topic of this book - what you think you attract - is something I hold dear to my heart, and therefore would recommend reading this book if you've ever questioned what point it has to be an eternal optimist.
