I realy enjoyed Sir Ken Robinson's book which is highly readable and talks about the concept of finding one's true calling in life (which he says, is the point at which one's talents overlap with one's highest passions - 'the Element'). This he does, through the telling of people's stories. It is inspiring stuff for those who want to believe the quote from Confucius - "If you enjoy what you do, you'll never work another day in your life". The book introduces the topic wonderfully although readers should be aware that there is little within the book about how to actually go about pursuing your dreams, although I am sure this was intentionally outside the scope of the book (for that I'd refer people to Marcus Buckingham's excellent book 'Go put your strengths to work' and his video podcast with Oprah which is free on iTunes).
My one gripe (which is minor), is that the stories are all about immensely successful people (e.g.Paul McCartney, Matt Groening) which are amazing but it might of been nice to see a few 'real people' stories where people successfully pursued their passions and found happiness but weren't necessarily world beaters. If anyone interested in the book hasn't yet seen Sir Ken's TED talk I'd thoroughly recommend that you view in on YouTube.
