When did you last change how you lead?
Forty years of leading teams on four continents taught me one thing above all: the leaders who last are not the ones with the most answers. They are the ones who keep learning.
Absorb what’s new. Adapt how you lead. Upgrade, again and again.
And yes, the video is my AI twin. I practice what I teach.
