There's a leadership principle that Derek Sivers refers to as the "spark to a lone nut."

I mention this in my book, Mastering Your Fate.

A leader needs the guts to stand alone and look ridiculous, doing something that nobody else is doing.

They have to be doing something that is simple and easy to follow.

The first follower has the crucial role to show people how to follow. This first follower is the "spark" that transforms the lone nut into a bona fide leader.

But for a movement to occur, you have to have validation with the second follower. That's why the first two followers are critical. To be an effective leader, you also have to be an effective follower.
