"I've worked with farmers in Zimbabwe who've lost their lands. I've worked with people in Venezuela, under threat of kidnappings, whose external world is unstable. But they have very strong social connections with their family and friends. And as a result, they're able to maintain a greater level of happiness and optimism than I've seen from bankers, consultants, or salespeople who are on the road all the time, who follow jobs separated from their families, and, as a result, find themselves missing out on the happiness that comes from those very connections that they severed."
