What tribes are, is a very simple concept that goes back 50 million years. It's about leading and connecting people and ideas. And it's something that people have wanted forever.

A million years went by quick.

And it turns out that tribes, not money, not factories, that can change our world, that can change politics, that can align large numbers of people. Not because you force them to do something against their will. But because they wanted to connect.

Leaders lead when they take positions, when they connect with their tribes, and when they help the tribe connect to itself.

Nature got it right with the cranes. They have been around since the Eocene, which ended 34 million years ago.
