Within our dreams and aspirations we find our opportunities.

People can do more than they ever believe they can do. Physically, mentally, academically. You have to be pushed. It hurts. But it's worth it, and it's a great thing.

Boxing is the ultimate challenge. There's nothing that can compare to testing yourself the way you do every time you step in the ring.

When I was fighting, I would look to excite the crowds with a bolo punch or something taunting. Looking back, they were legal - but not sportsmanlike. I don't recommend another boxer try them. But we looked more to make the robot fights dramatic first and realistic second.

Looking back, yes, I made too many comebacks. But each comeback I was 100 percent sure that I would win. I never came back for the money, because I didn't need it. The adulation I was getting anyway in other spheres. But I'm a guy who likes to see how close he can get to the edge of the mountain - that's what makes me tick.

Boxing is individual, although there's a team concept because you need a great corner, you need a great trainer, you need a great prep man, you need all of these things, but it's more of a Mano a Mano; it's more you versus me. I miss that time in training camp and Dad and Mom cooking meals. It was one big family.

To say what I would have been if I wasn't boxing, I don't know why, but I always wanted to be an x-ray technician or a substitute teacher. Those two occupations always stuck with me, maybe because my substitute teacher didn't give us homework, or because I've always had x-rays of my hands.

I run with music all the time. I cannot run without my iPod. I have everything. Teddy Pendergrass. Luther Van Dross. Michael Jackson. Outkast. If an Usher song comes on and it's fast, I go fast.

I made the decision to turn pro, and I remember what Ali said to me: 'Get Angelo Dundee. He's the right complexion with the right connection.' He knew boxing. Our relationship was so genuine, so sincere.

I'm one of the most optimistic persons in the world. I always believed that - there's another shot, another chance. In boxing, I never gave up. I kept trying, kept trying. Even when things seemed so dim, I continued to push forward to make something happen in my favor.

In Italy, I had an Afro, and a lot of the kids came up and felt my hair. It really was funny. I wish I had understood Italian.

Boxing should focus on pitting champion versus champion - those are the fights that everyone wants to see. The sports also needs to work on developing new heroes and personalities. I'd like to see more vignettes on fighters, focusing on their lives, goals and stories. Boxers need to be larger than life.

I never met a person as determined as my mother. From working hard for six kids to just trying to keep the household down or maintain my father's discipline, my dad, I'm so much like my father too. My father was so introverted, quiet, shy, nice. I got attributes from my father and mother.
