The book is a quick read and very helpful in getting one to think about one's strengths and the potential complementary strengths to look for in others to offset one's weaker areas, if you work in a team environment. However, once I completed the online test and obtained the resultant reports, I was shocked to learn that I would only get the Top 5 Themes, and the other 29 remain a mystery. Upon contacting the company, I learned that for an additional $550.00 I could then obtain the other 29 themes, as well as their order of ranking. It is obvious to me that this book is being used as a sales "hook" to try to get you to spend more money with the company and may also be being used as a "beachhead" sales device to penetrate into potential corporate accounts. I was not surprised or enlightened at all by the results, as I have been through a number of these types of profiling and behavioral characteristics tests over the years. However, they were "somewhat" useful to reconfirm some of my prior findings as still being current as of today. I would recommend the book and online test if you have never been through something like this before. They are quick and very easy to use. Just be aware that the top 5 themes are only a glimpse of your total "being" and the other 29 are just as important to your knowledge about yourself. However, unless you are willing to cough up another $550.00, you may end up disappointed and still a bit "in-the-dark" about your overall strengths. Good luck.
