I love love loved this book! It was like Imagine on crack (and much more applicable to real life). I feel like I learned so much and it could be applied to any area of life. It begins with the basis of habit and what happens in your brain when you are learning something new vs after you have been doing the same thing for a while and know what to expect (a "reward"). My mind was quite frankly blown learning that brain activity levels spike before a reward is earned when an activity is done out of habit. Duhigg used the examples of monkeys and juice, and rats/mice and cheese. It also explains why I, at least, have a tendancy to "space out" when doing extremely repetitious things (like my job)...it is a habit. Then Duhigg moved into specific people/situations where habit occurs and why addictions (habits!) are hard to break. I definitely recommend...!
