Happiness is our natural state, for each of us and for humanity as a whole, argues John Izzo. But that happiness is being stolen by insidious mental patterns that he depicts as thieves: the thief of control, the thief of conceit, the thief of coveting, the thief of consumption, and the thief of comfort. He discovered these thieves as he sought the true source of happiness during a year-long sabbatical, walking the Camino de Santiago in Spain and living in the Andes of Peru. This thoughtful and inspiring book describes the disguises these thieves wear, the tools they use to break into our hearts, and how to lock them out once and for all. Izzo shows how these same thieves of personal happiness are destroying society as well. This book will help us all discover, develop, and defend the happiness that is our true nature while creating a world we all want to live in.
