Though a lot of the information about EQ is purely scientific, this book speaks to the hearts of a wide audience... Daniel writes understandable and strong about the roots, sense and well use of EQ. He uses every day life examples to make it utterly vivid, compared to most scientific readings I know. The subject is endlessly relevant for anyone interesting in making more out of their lives, social contacts, self knowledge, succes in the field of work, dealing with emotional life and over-all progress... No matter what age, background, race or believes you have, this book WILL add to whoever you are! Don't feel sursprised reading this book twice, or even triple... I haven't found truth like this since reading the Bible ;) For people interested about the use of EQ in the field of work... See: Manfred Kets de Vries' The leadership Mystique! Another feast for the never-done-learning-mind!
