Most military cultures — and people in general — seek to impose values and control over what they encounter. What made the Mongols different was their ability to weigh each situation objectively, and if need be, swap out previous practices for new ones. All great businesses start this way, but then something happens. Take the theory of disruption, which posits that at some point in time, every industry will be disrupted by some trend or innovation that, despite all the resources in the world, the incumbent interests will be incapable of responding to. Why is this? Why can’t businesses change and adapt? A large part of it is because they lost the ability to learn. They stopped being students. The second this happens to you, your knowledge becomes fragile.
The ninetime Grammy– and Pulitzer Prize–winning jazz musician Wynton Marsalis once advised a promising young musician on the mindset required in the lifelong study of music: “Humility engenders learning because it beats back the arrogance that puts blinders on. It leaves you open for truths to reveal themselves. You don’t stand in your own way. . . . Do you know how you can tell when someone is truly humble? I believe there’s one simple test: because they consistently observe and listen, the humble improve. They don’t assume, ‘I know the way.’” No matter what you’ve done up to this point, you better still be a student. If you’re not still learning, you’re already dying.
