It’s a tribute to self-confidence, a motivational-poster caption with a hundred different photos just featuring Muhammad Ali.
On the mural, Ali is quoted, I said I was even before I knew I was.” Here’s the more commonly-accepted version:
“I am the greatest. I said that even before I knew I was. I figured that if I said it enough, I would convince the world that I really was the greatest.”
Can you guess? It’s difficult to pin down a solid attribution for the quote. I have little doubt he said it — but can someone say where?
