The creative act always requires a stepping back. It's called the incubation period. The incubation period - one of the four phases of creativity - is when you're not consciously thinking of a problem, and you're letting it marinate. So this is why you hear time and again, people saying they had that "Eureka" moment in the bath, like Archimedes, or in the shower, or while going for a walk or in a coffeehouse.

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.

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.

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.

[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.

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.

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."
