This book should be required reading for all humans. In school, one learns spelling, math, etc., and yet the very subject with which one is challenged in life - in any occupation, at any socio-economic level - namely stress and anxiety...this is not addressed. How often, if ever, is such a course on how to let go of worry & anxiety offered, let alone required, in grade school or college?
Read this book, treat it as a life-manual, apply the teachings...you'll be so better off for it. It's what we should all be taught before and with everything else in life. You will gain much from this book.
