Fear and the thought of failure . . . But we don't really know what fear is. Fear is something that we create in our own minds. Fear could be like fire. You can use it to heat you up, keep you warm, cook your food. There are so many things you can use it for. But if you allow it to go out of control, it will destroy you and everything around you.

God lets everything happen for a reason. It's all a learning process, and you have to go from one level to another.

You can’t be disturbed by anything. There’s no emotion involved. You can’t feel sorrow, you can’t feel pity, there’s nothing you feel. The job has to be done.

In the scheme of life, in emotion and loss, I responded the way I did. I lost. I shouldn't have responded that way. I've had some people tell me that I did a great thing - sticking up for myself - but to me, personally, with the way that I handled my emotions, I lost. But I learned. That will not happen again.

It's interesting that you put me in the league with those illustrious fighters [Muhammad Ali, Joe Louis, Jack Johnson], but I've proved since my career I've surpassed them as far my popularity. I'm the biggest fighter in the history of the sport. If you don't believe it, check the cash register.

I may have smoked too much weed, but I wasn't taking drugs or anything.

I felt the same fear in my first fight as I did in my last fight. It never goes away.
