The market is crowded with self-help books, why should you be excited about this one? Because this book is different. Cognitive science researchers have made a number of important discoveries about the ways our minds work that are potentially relevant to our daily lives. Markman, a leading cognitive scientist, has done an excellent job translating this research into useful advice to help you understand how to change habits. He outlines just enough of the results and principles to clarify why the practical advice he provides makes sense. (For readers who want to know more, there are key entry points into the literature in an appendix, a nice bonus for the curious.) The writing is crisp and clear, with examples that help illustrate the points without belaboring them.
