content: I found the book to be rather difficult to use. I felt that much more of the book could have been devoted to personality tests and relating them to your career. The tests that are included in the book are often shortened versions of what is available on the internet. If you are not very good at evaluating yourself this may be helpful, but I don't recommend it. The book plugs an on-line test at keirseycampbell.com repeatedly, even offering a discount coupon. I would say, just go straight to the website and take the tests there. They are much more comprehensive and take much less time.
