As a boxer I took the liberty of using not only my fists, but also my head.

Boxing and chess are similar. It’s about the choice of means. Sometimes I need a pawn, a bishop or a knight to defeat my opponent. It’s about finding the best way. A good boxer has to be variable. He doesn’t just need to know how to punch. He must also know how to protect himself, how to defend, how to avoid the opponent’s punches. Only a complete fighter can become champion.

Action is what separates the do-ers from the dreamers.

The fact is that Mike Tyson bit through my trousers and took a significant piece of flesh out of my thigh.

The mission I set out on in the beginning - to become heavyweight champion of the world, undisputed, lineal champion - you could say that mission is complete.

Now I am ready to set new goals and start a new career for myself outside of the ring.

Boxing isn't just about brute strength; it's about skill and outwitting your opponent.
