Contributor(s): Richard Stengel | For nearly three years Time magazine editor Richard Stengel collaborated with Nelson Mandela on his autobiography and travelled with him everywhere. Eating with him, watching him campaign, hearing him think out loud, Stengel came to know all the different sides of this complex man. He became a cherished friend and colleague. Now he has distilled countless hours of intimate conversation with Mandela into fifteen essential life lessons. In Mandela's Way, he recounts the moments in which 'the grandfather of South Africa' was tested and shares the wisdom he learned.
