I have read this book and this critic loves it! For years I have wondered as to why people in the same environment, setting, city, and even family can come out so amazingly different. This book teaches its reader how to classify and analyze people so that you can find out their point of reference on life and understand what they value and treasure in life. If you know a person's needs you can more easily meet their needs and help them. This book gives solid, practical advise on how to recognize and appreciate a person's psychological/emotional/volitional makeup as well as how to cope with and appreciate the differences in us all. Do you want to know why your super-energetic life-of-the-party friend retains his outlook on life no matter what? Do you want to know why Mr.Domineering feels that he MUST be in charge in spite of all adversity? Do you want to know why some people seem to be so gifted and deep even in the most shallow pools of life? Do you want to know why some people are content to stay introverts all of their life and are happy that way? Well, you'll just have to get the book and enjoy finding out!
