Frazier was not a big man at all. Frazier was about 5'9, but he would make anyone run. Put up your dukes and cover up because he's coming. He never backed up from anyone.

Growing up poor, I didn't even have a lunch to take to school. Lunch was 26 cents, and we didn't even know what 26 cents looked like. I didn't love school because I wanted to disguise that I was poorer than everybody else.

In 1973 I became heavyweight champion of the world with 38 victories, no defeats as a professional. You get to a point where you think you cannot lose. I felt like I had the greatest power with my fists, I was the strongest man in the world.

Iron' Mike Tyson is the last boxer who was truly embraced by the media. They followed him around. You didn't know what he was going to do next: bite you, cut you, fight you. When you think about it, that defines him - it was an exciting adventure.

It is painful to watch children trying to show off for parents who are engrossed in their cell phones. Children are nostalgic for the 'good old days' when parents used to read to them without the cell phone by their side or watch football games or Disney movies without having the BlackBerry handy.

A lot of people, most people who are working, they do it for money. And I'm not saying there's anything wrong with that. It so happens that I made a lot of money already, so I don't have to worry that much about it. I wouldn't fault anybody for doing it for the money, but it doesn't interest me right now.

As an artist, as a brand, as a rapper, as a musician, you know you got a window and a lot of people, even an athlete; they don't have no exit strategy. It's just living in the false reality that it's going to be like this forever.
