What's important at the grocery store is just as important in engines or medical systems. If the customer isn't satisfied if the stuff is getting stale if the shelf isn't right or if the offerings aren't right it's the same thing. You manage it like a small organization. You don't get hung up on zeros.
Producing is so exciting because you can enable things to happen whether it's like discovering a filmmaker who you're taking a chance on protecting a battle and driving home at the end of the day just going 'I'm so glad I stayed late at work and fought hard for that. Had my passion. Won that battle.'
