Understand: people will constantly attack you in life. One of their main weapons will be to instill in you doubts about yourself – your worth, your abilities, your potential. They will often disguise this as their objective opinion, but invariably it has a political purpose – they want to keep you down.

Things like reading a book or learning a language, or taking a walk - they're not stimulating. Your mind has to sort of learn how to deal with that kind of stimulation on its own. So that's a very important form of adversity.

When people are too present, too familiar or too in our face, something happens to us psychologically. We begin to tune them out, we begin to get sick of them, we begin to know them so well and become so familiar with who they are that we loose a bit of respect for them. You pass a certain threshold with the fact that you're too present in their lives, too much in their face and once that threshold is passed you're never going to repair it they have lost a certain respect for you.

The key to power, then, is the ability to judge who is best able to further your interests in all situations. Keep friends for friendship, but work with the skilled and competent.

Actually learning ancient Greek was a brilliant practice of mine because you'd sit there and you'd read a sentence and sometimes it would take you a day, an entire day to figure out one sentence. But it really trains you to be analytical, to think in a certain way to try and interpret what something means. So I've been thinking like that my whole life and then I love Machiavelli and I love thinking about politics that way. So it's sort of all that put together and then the good luck to meet a man who is sort of interested in the same thing.

I really do think you shoot for that beautiful experience of showing your movie in a crowd or room full of people, or even just one person who happens to go to a matinee screening.

When you have any kind of success in life, that's like the most dangerous moment that you're in because you're going to tend to think wow, I can just keep repeating what I've done. I'm a great person. People love me. All of the sudden they're giving me all of this attention. You get drunk on it and you lose your sense of balance and your sense of detachment. I know it's happened to me.
