Einhorn believes it is the single most important factor in achieving success and satisfaction. Contrary to the cynical axiom, "nice guys finished last," Einhorn makes the case that being a good person can make you happier, richer, more successful and fulfilled. Kindness is not always easy to put into practice--in all of life's dilemmas, we calculate, whether consciously or subconsciously, what the consequences of our behavior--good or bad--is likely to be. It is this ethical intelligence that Einhorn helps the reader cultivate through five exercises, which will help readers tackle setbacks while reaping the benefits of being kind.
