Thirteen spines, because thirteen has always been the number. Not the 728 — these are the ones where the idea is still in my head years later.

Three things I keep coming back to
The three o’clock test
Wake someone off the frontline at three in the morning and ask what the change is. If they cannot say it in one sentence, it is too complicated and it is already dead.
Learned by hiring badly
Periodization
Nobody sprints continuously and still does their best work. People need time to wander and think, and then they can sprint. Pressure only where it earns something.
Six years coaching athletes
Start from the commonality
Everyone fixates on the differences. A coordinator in Japan and one in the United States have far more in common than not. Prove what is shared, then personalize the remainder.
Twenty-five nationalities, one process
