The narcissist spends endless hours bragging about his genius and the cesspool of stupidity in which the rest of us exist. He once explained to me that if he told himself something enough times, it would become real.
While I understand the benefits of positive affirmations, they don’t change falsities into truth. I can still picture the narcissist sitting there telling himself he is a genius, an innocent victim, and an excellent father, but that doesn’t make it so.
You are who you are, and you did what you did. Nothing you say or think will alter that until you take responsibility for your actions and strive for change.
