In boxing, you get hit, it's painful, then you sit on the stool when the adrenaline is gone and you feel that pain. And then you fight the next round.
A wartime C.E.O. may not delegate. They make every decision based on the next product release. They may use a lot of profanity.
You can't worry about the mistakes, because you're going to make a lot of them. You've got to be thinking about your next move.
