During a philosophical evening conversation about the many troubles in the world, Mark Boyle realized that each of the many issues he was discussing with his friend shared a common root cause: money. Inspired by Mahatma Ghandi’s quote, “Be the change you want to see in the world,” Mark, then a successful businessman, resolved to live for a year without spending or receiving any hard cash. After successfully living moneyless for a whole year, Mark decided to continue living like that for two further years. As he now claims, this turned out to be the most fulfilling period of his life. “I’ve now more friends in my community than ever, I haven’t been ill since I began, and I’ve never felt fitter. I’ve found that friendship, not money, is real security. Most western poverty is psychological. Real independence is interdependence.”
