I just have this thing inside me that wants to eat and conquer. Maybe it's egotistical, but I have it in me. I don't want to be a tycoon. I just want to conquer people and their souls.

Fear is the greatest obstacle to learning. But fear is your best friend. Fear is like fire. If you learn to control it, you let it work for you. If you don’t learn to control it, it’ll destroy you and everything around you. Like a snowball on a hill, you can pick it up and throw it or do anything you want with it before it starts rolling down, but once it rolls down and gets so big, it’ll crush you to death. So one must never allow fear to develop and build up without having control over it, because if you don’t you won’t be able to achieve your objective or save your life.

I just don't have the desire no more, I don't have the stomach to do it no more. I don't even kill insects in my house. I just don't kill anything no more. I used to kill pigeons, rip their heads off, 'You dirty rat pigeon!' I don't even have the heart to kill an animal no more. I just changed my whole life in general. That probably could have changed the way I fight.

I earned that the strong will always beat the weak, but the smart will beat the strong. Boxing is a tough guy sport. But in the end, the tough guy gets to clean the streets and be a bodyguard. In the ring, the tough guy is going to get hurt; at the end of the day, he's going to talk funny. Only the smartest win. So, I know it's cliché, but power - real power - comes from knowledge, comes from smarts.

I don't know that person anymore, that guy in '86, '87. I don't know that guy no more. I don't have no affinity for that guy no more. I have no affinity for the guy who said, 'I am the greatest fighter God produced.' I have no affinity for the guy who said he would try to push his [opponent's] nose bone up into his brain. I just don't know that guy. I don't know who he is. I don't know where he came from. I don't have no kind of connection with him no more.

I have to always make sure I don't stay in one place and spend too much time one subject. I have my wife tell me [through an earpiece], "Come back! You're taking too long on that subject." I need to be reeled in.

I feel bad about my outlook, how I feel about people and society, and that I'll never be part of society the way I should.
