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

The only way to maximize group creativity—to make the whole more than the sum of its parts—is to encourage a candid discussion of mistakes.

We can only get it right when we talk about what we got wrong.
