Ali's belief in himself was something I picked up on, and it's become my own philosophy.

You get these moments in the ring that live forever. That's what Muhammad Ali accomplished, and I hope that I have, too.

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. On the downside, you meet a lot of really bad people in boxing, at all stages of your career.

Boxing was the only career where I wouldn't have to start out at the bottom. I had a good resume.

I'm regularly speaking at London Business School and Harvard Business School. They're the next generation of leaders in the fashion industry.

I want to really study and learn about fashion, and kind of discipline for a few years, really start to study, and then probably start my photography career. I feel like that'd be really good for me - to disappear for a few years.

It's been a constant struggle with my athletic career to identify myself as a child of God and understand that His love is unconditional for us; it's not conditional like fans, or coaches, or even myself.

I went to an ordinary school in New York City with no other actors. I learned to compartmentalise different parts of my life. I was one person at home and then another person at work and for that reason my career didn't challenge my family life.
