To say it bluntly, on average people with high EQ are more successful than people with high IQ. (There's a whole book about it.)
Also, is this book something you'd recommend to someone who's just casually interested in the subject?
Edit: Though it's been a while since I read it last, I remember finding it very informative and insightful. I don't think you need to be a psychologist or neuroscience expert to read it and benefit.
