"So the greatest source of happiness is other people- and what does money do? It isolates us from other people. It enables us to build walls, literal and figurative, around ourselves. We move from a teeming college dorm to an apartment to a house, and if we're really wealthy, to an estate. We think we're moving up, but really we're walling off ourselves."
— Eric Weiner (The Geography of Bliss: One Grump's Search for the Happiest Places in the World)
