If you really want to understand yourself, you should not identify with your Facebook account or with the inner story of the self. Instead, you should observe the actual flow of body and mind. You will see thoughts, emotions, and desires appear and disappear without much reason and without any command from you, just as different winds blow from this or that direction and mess up your hair. And just as you are not the winds, so also you are not the jumble of thoughts, emotions, and desires you experience, and you are certainly not the sanitized story you tell about them with hindsight.
