The Myers-Briggs Type Indicator is a personality test based on Jungian theory. In a nutshell, it states that every person falls into one of sixteen categories, and each one of these categories or "Types" has distinct needs, ways of interacting with others, manners of processing information, etc.
"Do What You Are" attempts to help individuals plot their own careers based on their own Myers Briggs "Type." Before finding this book, the only other career-related thing I had read was "What Colour is your Parachute," which was terrific. But I loved "Do What you Are" because it stated something that is so rarely said today... that you should find a job and career that suits who you really are. I passed this book around to all my friends and family, and most (but not all) loved it, too.
Something I found particularly delightful was that it affirmed a lot of things I had been thinkingabout my own situation, but had considered "unimportant." My type is "ENFP" (I know it might sound like jibberish to you now, but it will make sense if you read the book). This is a type that thrives on creativity, feels confined by rigid rules, and needs lots of friendly social interaction on the job. But, since I have a high IQ and did well at school, others have constantly tried to push me into "status" fields like medecine and litigation. In my heart, I had always felt those kinds of careers would kill me, but I couldn't really articulate why. After reading "Do What you Are," I was better able to accept my instincts and explored PR, fundraising, and finally settled on a job in publishing. I LOVE my job, and although I think I would have arrived here eventually, I do think that it would have taken me twice as long to arrive had I not read this book.
