NCLA Review -In many ways this book is a sequel to Florence Littauer’s classic bestselling book, Personality Plus. This latest book written with Rose Sweet is intended to help the individual succeed at work. The secret comes from discovering how to understand the four different personality types derived from Greek physician and philosopher Hippocrates. He examined the body fluids in each of his patients and postulated four personality types: sanguine, choleric, melancholy and phlegmatic. At first I was skeptical but as I continued reading I became convinced of the validity of the insights contained within this book. Whether you manage a giant corporation, work in an office or factory, or volunteer in a church or community organization, these insights for understanding personality types, including your own, will revolutionize how you deal with relationships with everyone you encounter. A personality profile is included at the end of the book so that the readers can determine their main personality type. Rating: 3 —MF ( )
