With a huge list of examples,  Dan & Chip Heath explain how to manage the changes for yourself, your family, friends or employees. They provide insights on how your brain, your mind are working to understand the change and accept it and work with it. Setting the concept of the elephant and the conductor, they give tips to understand many common behaviours which each of us is facing. Knowing that, they give tools to improve you own motivation or the motivation of others. 
This book is pretty useful for our day to day life at work, at home or any other situation as changes are everywhere.
He is helpful in better understanding our own reaction and attitude and also the ones of others.
