From Jonah Lehrer’s Imagine: How Creativity Works 

If I were to pick one element of Pixar culture that has led to its immaculate track record of success, it would be the embrace of failure. Pixar realizes that failure is an essential component of the creative process, that there is no shortcut around it. And that’s why their iterative process is all about identifying those failures as fast as possible, whether it’s in the morning production meeting or when testing out the first drafts of the story. After five hours of being obsessed with mistakes, going through iteration after iteration, it’s possible to create a really good 90-minute cartoon.
