Amazing book! This book includes a (really) brief preference-based test which yields a sort of personality profile that is then linked to career matches. I'm usually totally skeptical of these kinds of tests/books, but this one really nailed my personality and gave me some incredible advice about my career path and my future. My whole office has taken the test and everyone agrees that it's really useful for self-awareness and also for learning how to interact with people in the office who have different working styles. I actually met the author, and she's a pretty incredible lady. I high recommend the book!
