Love is just another name for what never gets old. - Jonah Lehrer

In fact, even fleeting feelings of delight can lead to dramatic increases in creativity. After watching a short, humorous video — Beeman uses a clip of Robin Williams doing standup — subjects have significantly more epiphanies, at least when compared with those who were shown scary or boring videos. Because positive moods allow us to relax, we focus less on the troubling world and more on these remote associations. Another ideal moment for insights, according to Beeman and John Kounios, is the early morning, shortly after waking up. The drowsy brain is unwound and disorganized, open to all sorts of unconventional ideas. The right hemisphere is also unusually active.

The mind is made out of used parts, engineered by a blind watchmaker. The result is that the uniquely human areas of the mind depend on the primitive mind underneath. The process of thinking requires feeling, for feelings are what let us understand all the information that we can't directly comprehend. Reason without emotion is impotent.

Expertise is simply the wisdom that emerges from cellular error. Mistakes aren't things to be discouraged. On the contrary, they should be cultivated and carefully investigated.
