Jay Shaw argues that affirmations like "I am the greatest" only work if they match who you actually are. Muhammad Ali's confidence came from his training, mindset, and behavior, not from repeating words. Build the identity first, then the affirmations follow naturally.

People often bring up Muhammad Ali when I talk about affirmations. Well, Muhammad Ali said, I am the greatest. He absolutely did. But go watch Muhammad Ali. Watch the way the man walked in a room. Watch the way he moved. Watch the way he competed. Listen to the way that he talked about himself. Do you really think Muhammad Ali was walking around saying, I am the greatest, because he was desperately trying to convince himself that he was? Or was that just what came out of Muhammad Ali? Because I think there's a huge difference between those two things. If I wake up tomorrow morning and start saying, "I am the greatest. I am the greatest. I am the greatest," I'm copying the words, but I'm not necessarily copying the identity that produced the words, and that's the mistake. We're copying the speedometer reading, but we're not building the car. When Ali said, "I am the greatest," it sounded like Ali. It matched the way that he carried himself. It matched his expectations. It matched the way that he trained. It matched the way that he competed. It matched what he imagined being capable. The statement matched the identity.
