I stole this book off of my brother's Christmas list this past year, and after my parents purchased it for me, my mom even bought herself a copy. Charles Duhigg, in The Power of Habit, writes a compelling case for how habits work, how we form habits (both with and without conscious thought), and how we can change our habits even when it seems impossible. Duhigg includes a number of anecdotal stories such as why Americans began using toothpaste after centuries of deeming it unnecessary. And no, it's not because we wised up and realized it was better for our health to brush our teeth - you'll be amazed at what the reason really is. There's plenty of hard science in the book to satisfy those who want to know where in the brain habits form and how they do so. However, the book is not bogged down with so many statistics and scientific jargon that it would keep anyone from enjoying and learning from it. If you have any interest in why we do what we do, day in and day out, and how we can alter our own habits, The Power of Habit is a fantastic read.
