Bests & Worsts Reviews from Amazon

I normally never post a review on Amazon, but in this case I simply could not stop mysefl from posting it, as I had great expectations about this book after seeying the TED talk of Ms. Duckworth and hearing a Freakonomics podcast with her. In the end, I was disappointed. Please also excuse grammar/ spelling, as I'm writing this from Russia and I'm not a native English speaker. This book tells us that grit (and not talent or luck) is essential for success in life. The reader will find multiple anecdotes on how so-and-so achieved much by perseverence, passion and not giving up. So half of the book is dedicated to showing a reader how important is grit for success (quite convincingly, but to my taste, way too extensively; couple of anecdotes and studies mentioned would have done as good as these several chapters). Along with anecdotes some (quite robust) scientific evidence is given. What the book lacks completely, is scientifically based advice HOW TO BUILD GRIT. As someone, who struggles to be gritty in my daily life, I had great hopes to find valuable hints in this book. There are a few, but very "soft" ones (like the author assumes they should work, but being honest with the reader, concedes that there is no evidence behind these tips).
