What I want to achieve in boxing is worldwide. I want to show I'm not just a British commodity... To do that, you have to fight the best and fight all over the world.
It's boxing. It's about getting people interested. If I didn't say some stupid things from time to time, there wouldn't be that many people interested in me. But I let my fists do the talking when the bell rings.
You need to stay hungry and not allow someone like John Ruiz to come over and mess you up in front of all your fans.
In 2000, I got stuck in the sea off Cyprus after I fell off a boat. I was out there for over an hour. I am not a strong swimmer, but adrenaline kicked in, and I swam back.
I would fight till I'm dead. This is why I am here. I am put on Earth to fight. I feel it deep in my waters.
I would love to have gone there, fight at Madison Square Garden or a casino in Las Vegas, but there are no American heavyweights now who can pose a challenge to me.
Only time will tell whether the Klitschkos need me more than I need them. They won't believe that. But it depends what they want out of boxing. If they want guaranteed easy victories, then they can do what they've always done, but if they want a tough challenge, you'd think they would want to beat down my door.
I've been in the ring with the Bronze Bomber, Deontay Wilder. I've tasted his power, and he's tasted mine.
