Perhaps it's true you can't go back in time, but you can return to the scene of a love, of a crime, of happiness, and of a fateful decision; the places are what remain, are what you can possess, are what is immortal.

It is a fact of human nature that we derive pleasure from watching others engage in pleasurable acts. This explains the popularity of two enterprises: pornography and cafés.

Perhaps it's true you can't go back in time, but you can return to the scene of a love, of a crime, of happiness, and of a fateful decision; the places are what remain, are what you can possess, are what is immortal.

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.

Where we are is vital to who we are.

Haydn, Beethoven, Mozart, none of them were born in Vienna. They all moved there. It became a magnet, but what made it magnetized in the first place? There has to be a seed there. In the case of Vienna of about 1780, it was this deep-seated love of music.

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.
