But the real power of the book is realized when it is distributed to others, hand to hand. Since the actions of those around you can profoundly affect your life, you are improving your own survival when you present copies of The Way to Happiness to friends, associates, employees and customers. In this way, you help others survive better and lead happier lives. They, in turn, pass copies of the book to those whose lives they influence, encouraging others to treat their fellows with kindness, compassion and respect.
And so it goes, moving from person to person, helping others to live better lives.
