“It takes no effort to be ordinary. Ordinary is not even a challenge. You can do nothing and be ordinary.”

I’ve got a history of frustrating guys and making them angry.

There’s no great person that lived that didn’t go through scrutiny or ridicule and prosecution in all types of ways, to be who they are in history.

Prison is a thing where talking gets you killed. What gets you respect is you do. The guy that you fear is a guy that says nothing.

I didn’t need to take any fight for the last 10 years. But I’ve always fought the best and I’ve always wanted to prove myself to the best.

This is a great position to be in. I don’t really believe there is any fighter, in any decade that can be in my position of luxury that I’ve been in for many years.

I don’t know what being a 48-year-old feels like. There are a lot of 48 year olds that aren’t in good shape. The pharmacy is making a killing off of them.

This fight isn’t about boxing, it’s something deeper than that.

There are so many things I’ve done that the world of boxing has witnessed. It’s going to be difficult for the boxing people to pick one of my performances as the best.

There’s always a chance you will see something new in a fight. Especially in boxing.

The powers that be don’t want athletes or boxers to become as smart as they are.

I was made to be where I’m at. I just had to go through some challenges, so that I can educate others later.

I would never let a white boy beat me. You can print that. I would never lose to a white person.

Tavoris Cloud might actually be hungrier than me. How often do you hear a fighter say that his opponent is hungrier than he is? I don’t need hunger. I’m motivated by my desire to prove that I’m different and that I can still silence the critics.

I’m lining up my troops to go to battle with. Tarver is the man at light heavyweight. He has the credibility of the fans and media, and that’s what counts. That’s why I am taking this risk, but I am taking it by preparing myself with good people.

I must destroy everybody that comes in front of me. I must execute them and I must do it in grand style. I must slay Robert Allen like I must slay De La Hoya or anybody else that steps in that ring.

We are creatures that are designed for continual challenge. We must grow or we begin to die….So just standing still isn’t really an option. We have to move on. If not, disturbances will come.

Climate change does not respect border; it does not respect who you are – rich and poor, small and big. Therefore, this is what we call global challenges, which require global solidarity.

Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.

The challenge of warriorship is to step out of the cocoon, to step out into space, by being brave and at the same time gentle

My dad challenged every president from President [Dwight] Eisenhower and Vice President [Richard] Nixon to President [J.F] Kennedy.

You only have temporary curiosity, amusement, and challenges, but that does not necessarily mean you are really convinced that it’s necessary or that it’s not even worth to do it.

If the imagination is to transcend and transform experience it has to question, to challenge, to conceive of alternatives, perhaps to the very life you are living at the moment.

I wasn’t searching for a common denominator – I started wondering about the challenge of working in other cultures. What I reached was the sudden acknowledgment of the universal aspect of filmmaking.
