"I am the Greatest"
/I loved Muhammad Ali - what he stood for for me - pure passion, athletic ability (albeit boxing), entertaining commentary, and a strong committment to his personal convictions. I suspect he will be immortalized, like Elvis Presley, or maybe even Martin Luther King.
Very few of us, could get away with constantly claiming "I am the greatest", but what a great driving affirmation. I think of the www.values.com video about optimism called The Greatest - we should all delight in such optimism.
