The coffee shop played a big role in Vienna of 1900. Rents were sky high, housing was difficult to come by, your apartment probably wasn't heated, and so you went to the coffee shop. You went to the coffee shop because it was warm, because it was great Viennese coffee, and you went for the conversation and the company.

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.

The word "utopia" has two meanings. It means both "good place" and "nowhere". That's the way it should be. The happiest places, I think, are the ones that reside just this side of paradise. The perfect person would be insufferable to live with; likewise, we wouldn't want to live in the perfect place, either. "A life time of happiness! No man could bear it: It would be hell on earth," wrote George Bernard Shaw, in his play Man and Superman.

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.

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.

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.

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.
