Every single person, every single organization on the planet knows what they do, 100 percent. Some know how they do it, whether you call it your differentiated value proposition or your proprietary process or your USP. But very, very few people or organizations know why they do what they do. And by “why” I don’t mean “to make a profit.” That’s a result. It’s always a result. By “why,” I mean: What’s your purpose? What’s your cause? What’s your belief? Why does your organization exist? Why do you get out of bed in the morning? And why should anyone care?

Sinek says that the limbic brain corresponds to leadership in the following way:

The neocortex is responsible for all of our rational and analytical thought and language. The middle two sections make up our limbic brains, and our limbic brains are responsible for all of our feelings, like trust and loyalty. It’s also responsible for all human behavior, all decision-making, and it has no capacity for language.

Why it’s important to know why you do what you do:

But if you don’t know why you do what you do, and people respond to why you do what you do, then how will you ever get people to vote for you, or buy something from you, or, more importantly, be loyal and want to be a part of what it is that you do. The goal is not just to sell to people who need what you have; the goal is to sell to people who believe what you believe.

People don’t buy what you do; they buy why you do it. If you talk about what you believe, you will attract those who believe what you believe.
