The fifth question of the Keystone conversation is how will we fix it when it goes wrong? There's something really powerful about having a conversation about how to get around to fixing this even before anything bad has happened. With a form of boss of mine, we agreed that we'd have what we call an off your chest session. And I might say, look, for me, if you just come up and say, 'I screwed up, I'm sorry' That's all I need.
