I've done both theatre and film and the fact is if you start believing, if you start reading things and they're good reviews - you believe that and you're lost, and then you read bad reviews and you think that's true and you read that and you're lost.
One of the things I've had the advantage of, growing up and being close to the top management of this company and other companies for most of my life, is seeing how CEOs start to believe in their own infallibility. And that really scares me.
