In Switch, Dan and Chip break down the essential parts of changing habits and behaviors. There are three parts to the process. First, you need to direct the Rider. The Rider is the rationale side of the brain. Second, you need to motivate the Elephant, the emotional/impulsive side of the brain. Lastly, you need to shape the path and make the process easy. I found the book very interesting, and I would highly recommend.
