We are shaped not only by our current geography but by our ancestral one as well. Americans, for instance, retain a frontier spirit even though the only frontier that remains is that vast open space between the SUV and strip mall. We are our past.

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.

God is not an exclamation point. He is, at his best, a semicolon, connecting people, and generating what Aldous Huxley called “human grace.” Somewhere along the way, we’ve lost sight of this.

You look around the world at geniuses, and they don't appear randomly, they appear in genius clusters. Athens in 50 BC, Florence 1500, Silicon Valley today. This is not a coincidence.

You need some reason why Beethoven, Mozart and Haydn in the 18th century all flocked to Vienna. What was it about Vienna? They must have known on some level that that is where they would flourish. It's what biologists call "selective migration."

what doesn't kill you not only make you stronger, but also more honest.
