Dear friends, if you repeatedly tell me how unlovable you are, I will, over time, come to believe it's true. That's the magic and the horror of propaganda and lies. Over time, with enough repetition, they become truth.
The corollary of this is, if you tell me how lovable you are, I will also come to believe that's true.
Tell the lie the benefits you, not the one that harms you. Eventually, it stops being a lie, either way.
