"Going back to my first career in the military, one of the things that was interesting was the military created a process of 'after-action reviews’. The after-action reviews are basically saying you've had this mission, you've gone out on this mission, whether it's a training mission or combat mission, and now you come back and you get the team together and you ask four questions. What did we want? What did we get? Why were they different? And what did we learn? If you think in terms of those four questions, that fourth one of 'What did we learn?' That's your stepping stone into the future. If you don't spend time on that, you're not going to learn. You're going to keep making mistakes."
