Because of my two films - one was about my half-sister (Kati with an I) and the next one featured my cousin (Fake It So Real) - I was hesitant to start with someone so close.

The idea of social performance, that we're always performing identities, is something I got fairly obsessed with. I think it's probably because I am a person who went to 15 different elementary and middle schools. I moved all the time, often having to run out in the middle of the night because my mom couldn't pay the bills. There were schools where I'd be the poor loser kid. There were schools where I'd suddenly be the smart kid or the cool kid, although that was very seldom.

50 is a great person. I was a little intimidated when I met him for the first time in 2006. I didn't know what to expect. It ended up we got along really well. That's why we decided to do a book together, The 50th Law of Power.

Most people have no sense of self-awareness. They're not aware of what they really want. They knew it when they were younger but then as they get older they listened to parents, they listened to peers and they think that, for instance, money is the most important thing when it really isn't.

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.

I have the point that everybody essentially have these unique set of DNA you have. There's something different about you genetically. You are unique is what I am trying to say - the combination of experiences and emotions you have felt are never repeated.

The moment people feel they know what to expect from you, your spell on them is broken.
