If you believe you are nil, you missed your life if you are always complaining that happiness, that can not happen, this book is for you! I found the personal development literature with skepticism, but this book convinced me. A priori, there is no major discovery in this book, all its principles are logical and take common sense. The fact remains that all candidates for a better life need to be convinced that this is possible. And there is nothing better than a little hammering principles not really gained finally! The sum to a word? Positiver! But it would be so simplistic. The book's approach is clear and progressive, that is what makes all that power. Do not underestimate! PS: its title in English is much better: Feel the Fear and Do it Anyway
