Ed Catmull, a co-founder of Pixar, believes that one the enemies of creativity is complacency. At first, he says, all their moves suck, so he sees his job as taking them from “suck to non-suck”.
For Ed Catmull creativity happens in the unknown and in the hidden. When you’re successful you might be tempted to think you’re doing things right, and make the mistake of stopping asking questions.
At Pixar, even when a film has been very successful they still subject it to strict scrutiny to see how it could be made even better.
By treating success as failure you preserve your best asset: your creativity. Success is not a destination: its just a result. How you get there is what matters.
