"Each of us plays four roles in relation to the brain. We lead, we inspire, we invent, and we use it. Most people do not actively use their brains. They passively let their feelings and thoughts control their lives. They don't invent new ways to use their brains, either, settling instead for the same routine and repetitive thoughts every day. But if you master all four roles, you create your super brain. When you are the active observer of your feelings and thoughts, you become the user of your brain. Your super brain then serves you, not vice versa."
