What if you have no idea what the truth is? What if you’re convinced that your lies are what really happened? … I’m a great believer in self-deception. If you asked me what makes the world go round, I would say self-deception. Self-deception allows us to create a consistent narrative for ourselves that we actually believe. I’m not saying that the truth doesn’t matter. It does. But self-deception is how we survive.
