Money matters but less than we think and not in the way that we think. Family is important. So are friends. Envy is toxic. So is excessive thinking. Beaches are optional. Trust is not. Neither is gratitude.

[Happiness is] a ghost, it’s a shadow. You can’t really chase it. It’s a by-product, a very pleasant side effect to a life lived well.

I've spent most of my life trying to think my way to happiness, and my failure to achieve that goal only proves, in my mind, that I am not a good enough thinker. It never occurred to me that the source of my unhappiness is not flawed thinking but thinking itself.

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."

I've always been a big believer in the power of place. I believe that where we are affects who we are when it comes to happiness, spirituality, economics and creative genius.

The late British-born philosopher Alan Watts, in one of his wonderful lectures on eastern philosophy, used this analogy: "If I draw a circle, most people, when asked what I have drawn, will say I have drawn a circle or a disc, or a ball. Very few people will say I've drawn a hole in the wall, because most people think of the inside first, rather than thinking of the outside. But actually these two sides go together--you cannot have what is 'in here' unless you have what is out there.' " In other words, where we are is vital to who we are.

I think we should have more coffeehouses, more cafes, more "third places." More places where people can get together that's not work, not home, and where they can interact with people who are different from them.
