Our happiness is completely and utterly intertwined with other people: family and friends and neighbors and the woman you hardly notice who cleans your office. Happiness is not a noun or verb. It's a conjunction. Connective tissue.

A Mozart symphony is very much like a Pixar movie - in the sense that Pixar movies are hugely successful because they operate on several levels at the same time.

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 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.

That's why we feel so disoriented, irritated even, when these touchstones from our past are altered. We don't like it when our hometown changes, even in small ways. It's unsettling. The playground! It used to be right here, I swear. Mess with our hometown, and you're messing with our past, with who we are. Nobody likes that.

For me, a place unvisited is like an unrequited love. A dull ache that- try as you might to think it away, to convince yourself that she really wasn't the right country for you- just won't leave you in peace.

Every country has its cocktail-party question. A simple one-sentence query, the answer to which unlocks a motherlode of information about the person you just met.... In Switzerland it is, Where are you from? That is all you need to know about someone.
