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.

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.

Part of positive psychology is about being positive, but sometimes laughter and clowns are not appropriate. Some people don't want to be happy, and that's okay. They want meaningful lives, and those are not always the same as happy lives.

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.

Normally, we think of the religious as people who care more, not less than the rest of us. This is not true, not exactly. The truly religious care more deeply about fewer things and do't give a hoot about the rest.

Don't forget that Mozart worked on commission. He almost always would write something if he knew exactly who was paying for it and where it would be performed. So you can't really separate the creation of genius from the appreciation of it.

If you walk into a coffee shop in 1903 Vienna, you might find at the same table the artist Gustav Klimt, Sigmund Freud, Leon Trotsky and possibly Adolf Hitler, who lived in Vienna at the same time.
