This is a fascinating book on the psychology and neurology of time. Pink explores how our bodies react at different times of the day. (Note: Never get surgery in the early afternoon!), the benefits of breaks and how we remember.
As I have always discussed with clients, humans are the only creatures who focus on the concept of future. Usually looking at the problems, issues and concerns they have. They react to people who can help make the future clearer, with less problems.
This book is a great read. Highly recommend it.
