A boxer should quit at the top, as they say. But that’s complicated. There are plenty of people in boxing who make money out off you. And they tell you that you’ve still got it, that it’s still getting better.

Whatever I do, I always want to get better.

After about 25 fights you don't always have to keep going to the bathroom before the fight.

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.

I am the heavyweight champion of the world, and the greatest heavyweight you have seen for a long while. With Tyson on the card, it is definitely an added bonus because Lewis-Tyson on the same card would be a great doubleheader. This is what the fans want to see.

There is just one rule about boxing: never bet on the white guy.

I've found that taking shortcuts will get you to the place you don't want to be much quicker than they get u to the place u want to be.
