"Leonardo Da Vinci used to travel with a small notebook hanging from his belt, and whenever something caught his eye, he would make a note, or begin sketching furiously.

"We live in an age that worships attention. When we need to work, we force ourselves to concentrate. This approach can also inhibit the imagination. Sometimes, it helps to consider irrelevant information, to eavesdrop on all the stray associations unfolding in the far reaches of the brain."
