I've just read a book by Jonah Lehrer called Imagine: How Creativity Works. It's an uplifting, upbeat rampage through creativity, innovation and inspiration.
At Saatchi & Saatchi, we are all focused on being True Blue rather than plain old green. Jonah tells us that being surrounded by the color blue doubles the output of the imagination. It makes us think of the ocean of freedom.
It got my vote.
He also advocates taking lots and lots of trips. "Travels frees us from the physical constraints of the imagination." I couldn't agree more. Almost all of my breakthrough thinking occurs when I'm on the road, far away from the familiar and the secure.
I also buy into his conclusion that frequent power naps result in more frequent ideas. When we are asleep and dreaming, your brain makes associations and connections it doesn't know how to when we're awake.
A book worth reading.
