The Golden Circle:

There are leaders and there are those who lead.
Leaders hold a position of power or influence.
Those who lead inspire us.
Whether individuals or organizations, we follow those who lead not because we have to, but because we want to.
We follow those who lead, not for them but for ourselves.

Simon Sinek has a simple but powerful model for inspirational leadership all starting with a golden circle and the question “Why?” His examples include Apple, Martin Luther King, and the Wright brothers — and as a counterpoint Tivo, which (until a recent court victory that tripled its stock price) appeared to be struggling.
