“Not too many people work in a job where, waiting out there are three or four hundred people who are paid to tear apart what you've done. And often they are brighter than you are, or they know more about the subject than you do, or they wish they had written a book themselves, or done a lot better. Or they just don't like it! And you have to live with it. I have been very well treated by the critics in the long haul.”

“I go through a lot of depression, and I know other people do, too, but I have an outlet that so many people don't. If you have that inside of you and can't get it out, what do you do?”

“I can read books and news articles about people who have excelled, people who have done extremely well in their chosen field, or made a lot of money, or married well, or what have you. When some people read this stuff, they get inspired, but when I read it, it makes me feel worse. Sometimes I wish I had never learned to read.”

“Having many cats is good. If you feel bad, you look at the cats and you feel better, because they know that everything is just the way it is. You don't have to be nervous about anything. And they know it. They are saviors. The more cats you have, the longer you will live. If you have a hundred cats, you will live ten times longer than if you have ten. One day, this will be known and people will have thousands of cats.”

“I don't think there are very many people that will have the experience of sitting in this room, doing a job, and the next thing you know you've been on every television camera around the world, and people are' they're frightened of you. They don't know what to make of you. I think people seemed to believe when they saw me that they might be becoming possessed. That is the look in their eyes. They were frightened of me. And no matter what I said or did, it didn't change. And the fact that it was a job in film, it just never came across. And I really' I wish that things had been different back then, but people couldn't see that it was entertainment.”

“If you can't do anything as good as or even better than what you have already done, then don't do it.”

“I don't do regrets. Regrets are pointless. It's too late for regrets. You've already done it, haven't you? You've lived your life. No point wishing you could change it.”

“No matter how much kids beg to be treated like adults, nobody likes to let go of their childhood. You wish for it and dream of it and the second you have it, you wonder what you've done. You wonder what it is you've become.”

“Too many songs have been written about love already, you know? Subject's covered.”

“People are jumping on [veganism] slowly but surely, but I think it’s cool. I think you’re a smarter and more intelligent fighter. Me and my brother are at the top of the game and have been for a long time. We’re obviously doing something right. Besides knowing how to kick somebody in the head, you should know how to feel good tomorrow. … I like to promote the vegan industry. I hear a lot of criticism from people saying you need meat to be strong and for recovery, and it’s a bunch of bullshit, because I train harder than everybody. It’s so easy to argue with these people. I’m like, ‘Dude, have you done a tenth of what I’ve done?”
