Knowledge can be a subtle curse. When we learn about the world, we also learn all the reasons why the world cannot be changed. We get used to our failures and imperfections. We become numb to the possibilities of something new

Creativity is not a trait that we inherit in our genes or a blessing bestowed by the angels. It's a skill.

The imagination is unleashed by constraints. You break out of the box by stepping into shackles.

What you discover when you look at creativity from the perspective of the brain is that it is universal. We're all creative all of the time, we can't help but be creative.

How do we regulate our emotions? The answer is surprisingly simple: by thinking about them. The prefrontal cortex allows each of us to contemplate his or her own mind, a talent psychologists call metacognition. We know when we are angry; every emotional state comes with self-awareness attached, so that an individual can try to figure out why he's feeling what he's feeling. If the particular feeling makes no sense—if the amygdala is simply responding to a loss frame, for example—then it can be discounted. The prefrontal cortex can deliberately choose to ignore the emotional brain.

We travel because we need to, because distance and difference are the secret tonic of creativity. When we get home, home is still the same. But something in our mind has been changed, and that changes everything. Several new science papers suggest that getting away is an essential habit of effective thinking. When we escape from the place we spend most of our time, the mind is suddenly made aware of all those errant ideas we'd previously suppressed. We start thinking about obscure possibilitiebsthat never would have occurred to us if we'd stayed home.
