More specifically, we follow leaders who connect us to a mission we believe in, who clarify what’s expected of us, who surround us with people who define excellence the same way we do, who value us for our strengths, who show us that our teammates will always be there for us, who diligently replay our winning plays, who challenge us to keep getting better, and who give us confidence in the future.

We have seen, already, that the best people aren’t well-rounded, but are instead spiky—they have honed one or two distinctive abilities that they use to make their mark on the world. What we see in the best leaders is a similar extremism—a few signal abilities refined over time. But now, these abilities are so pronounced, and the leaders so adept at transmitting them to the world, that they stand out to all of us. And so this truth: we follow spikes.

Each truly effective leader cultivates his or her mastery in a way that communicates to us something certain and vivid. It’s as if we trust leaders only when they’ve proven to us that they’ve opened more doors than we have, seen round more corners than we have, dived deeper than we have, taken themselves more seriously than we have. We trust the seriousness of this. We trust its predictability. We are drawn to its specialness. We sense its authenticity. We are attracted to the beautiful clarity of great ability, the brief moments of awe. We ignore everything else.

Leading and following are not abstractions. They are human interactions; human relationships. And their currency is the currency of all human relationships—the currency of emotional bonds, of trust, and of love. If you, as a leader, forget these things, and yet master everything that theory world tells you matters, you will find yourself alone. But if you understand who you are, at your core, and hone that understanding into a few special abilities, each of which refracts and magnifies your intent, your essence, and your humanity, then, in the real world, we will see you.

And we will follow.

This is because people follow a leader only when they see something that will turn anxiety about the future into confidence. Your mastery is, to other people, confidence-inducing. It shows them something specific and tangible about you, something vivid, not vague. It shows them that you are both an expert in who you are—and therefore who you will be no matter what situations you all encounter—and an expert in your chosen craft—and therefore are more likely to see around corners and be ready for whatever the future might hold for them. Both of these inspire confidence.
