The book is dedicated to all the people who don’t like stupid answers to their questions, or sweet nothings about their life. It is dedicated to those who seek extraordinary skills and results, despite the circumstances of their life, and to those who want to know who they can really become.
I wrote it, so rating is definitely biased. It's boring like most of my writings. It's empirical work. And I was amazed I've come up to conclusions without having access to any real scientific research at that time.
