Socrates admonished: "Know thyself." Within the first few pages of this book, it is obvious that this is the author's mission and message.
There are many books which cover similar ground as is set forth in this book. It is useful, nonetheless, because of the simple and straightforward manner in which the information is set forth. Everyone should engage in some self-analysis and attempt to come to a greater understanding of their own personal operating system. To that end, this book sets forth the four basic personality types and helps one to understand how they operate and react in different situations.
There are several books of this type in circulation, and multiple programs which attempt to explain the personality types and their interaction. This book is commendable because of the simplicity with which it presents the information. The book recites its lessons in a simple, almost allegorical, format. The flaw in the book is that it is almost too simplistic. Understanding personality differences and interactions is not a panacea for eliminating conflict, although it admittedly it will make interactions with others easier and more productive.
In the book, everything can move as productively and smoothly as it does because all partake of the training and education together, and share a common goal of "making difficult people disappear." Certain people, however, do not as easily assimilate and adopt such information.
The labels used are easily remembered and understood, which is aided by the acronyms used of the CORE MAP. This stands for the personality labels used (Commander, Organizer, Relater and Entertainer) in an effort to show how they can interact with one another (Multi-dimensional Awareness Profile). The ultimate analysis is very similar to other systems used for personality analysis, because there are still the same four basic personality types.
The point made here, of course, is how difficult people can be is in very large part determined by how we react to them, or otherwise interact with them. We can be our own worst enemies.
Ultimately, Socrates advice is well given. The better we understand ourselves, the better we are able to communicate and deal with others.
