Part I — The story
The story
Muhammad Ali was one of the greatest and most charismatic athletes in history — a three-time heavyweight boxing champion whose speed, skill, and showmanship redefined his sport, and whose boast that he was 'The Greatest' he spent a career proving true. He pioneered a kind of psychological warfare and self-promotion, predicting rounds and taunting opponents, that made him a global icon and changed how athletes marketed themselves.
But Ali's enduring greatness lies as much outside the ring. At the peak of his career he refused, on grounds of conscience and faith, to be drafted into the Vietnam War — a stand that cost him his title, his boxing licence, and nearly four years of his prime, and brought the threat of prison. He accepted the enormous cost rather than betray his principles, and was ultimately vindicated. He is a study in backing supreme self-belief with the work to prove it, and in the courage to sacrifice everything for conviction.

In their words
Float like a butterfly, sting like a bee.
Impossible is just a word thrown around by small men.
Service to others is the rent you pay for your room here on earth.
