Far better than the average popular psychology book, as Dr. Dweck's warrant for her framework is a much more robust line of research than, say, Dr. Grey's Mars/Venus cottage industry. It makes common cause with some of Malcolm Gladwell's writing, but is better for the author's direct involvement in the theory building research. Dweck is open about her struggles in attempting to craft a work for the popular press, which is refreshing, and many of the personal examples of growth and fixed mindsets she shares provide compelling operationalizations of her concepts at a more grounded level than the lab reports or accounts of the rich and (in)famous. Basically, it's not that a growth mindset is the only way to success, but those who are successful and NOT insufferable a**holes got that way through the growth mindset. Widely applicable to multiple disciplines and endeavors, the only thing keeping it from a full five-star for me is the inclusion of congratulatory letters to the author from people who've been helped by adopting a growth mindset. Those bits were unnecessary for demonstrating the power of Dweck's ideas, and gave portions of the book an air of a sales pitch, much like the anecdotal success stories in Disconnected Kids masked that book's holes. I don't think there are such holes here, but the letters to the author feel a bit unsavory.
