Boxing has been in my blood since I can remember. It comes naturally to me, and I've enjoyed it ever since I started, at the age of six.

There is always space for improvement, no matter how long you've been in the business.

Everything I have in this world, I owe to the sport of boxing, and I won't ever forget that.

I want to be able to look at myself in the mirror and know I took everyone on.

Every time I work out in the gym, every time I train, I know I'm going to do well. But I like surprising the fans, the critics, the people who doubt me.

As a professional athlete and someone who has spent almost his entire life in boxing, not a day goes by when I don't think about coming back, but I am retired, and after speaking to my family and following a great deal of introspection, I have decided to stay retired.

I was a little kid who used to fight a lot in the street-and get beat up.

I feel amazing. In my life right now, I have so much motivation. I am so hungry and so determined... I am young, I am healthy and I feel great - 42 is the new 32.

My dad has never once told me after a fight that I did well.

The fight life, that was easy. This is a battle I have every day.
