If you have a habit that you just can’t break, Duhigg’s research may tell you why. And it may even help you break it. By examining brain science and a wide variety of case studies, Duhigg shows how “cues and rewards” cause us to form habits. I found the personal pieces (i.e. nail-biting and cigarette-smoking) fascinating and had a harder time connecting the dots between habits of CEO’s and the resulting corporate culture shifts. But anyone who enjoys the Freakanomics books or anything by Malcolm Gladwell may want to add this to their summer reading—or listening—list.
