Well this book is good but not good enough. Because it truly puts you in a category and provides you suitable careers according to your personality type, i.e., what careers you'd possibly find enjoyable based on the functioning of your brain.But each type offers varied fields of career. For example, as in my INFP type, you could be an actor as well as a psychological counselor. That means you have to pounder into what your abilities and interests are before you can find the right career.Thus I worked with "Discover What You Are Best At" by Linda Gale, which shows your aptitudes(abilities) to narrow the focus. And now I've found the right direction thanks to both books.
