The mind is a real dangerous neighborhood to travel by ourselves.

My biggest weakness is my sensitivity. I am too sensitive a person.

I try my best to learn from other people's mistakes. I have a lot of respect for people who can change.

I just want to do what I do best, and that's fight. I love it.

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.

These books ain't window dressing. I think Machiavelli's the most sophisticated writer outside of Shakespeare. Way ahead of his time. Such a manipulative person. Everything he accomplished he did by kissin' ass.

There are not many regrets that I have. There are a few things that I wish I'd changed in my life, but they are not so dramatic that I'd go out of my way to change them. But I go back and think about my life so far periodically in my head.
