“Your personality is constantly changing, so if your personality is you, which person are you? Are you the angry person, the loving person, the frustrated person, the irritated person, or the kind person? You probably think you’re all of them, but you can’t be all of them because if you were, the angry person would never disappear; it would always be here. Or if the frustrated person were really you, when the frustrated person disappeared, a bit of you would disappear with it. But that doesn’t happen, does it? You’re here before the angry person appears, and you’re here after the angry person disappears. You’re here before the frustrated person appears, and you’re here after they disappear. Clearly you are not your changing moods or personality.”
