Think of it this way: There are two kinds of failure. The first comes from never trying out your ideas because you are afraid, or because you are waiting for the perfect time. This kind of failure you can never learn from, and such timidity will destroy you. The second kind comes from a bold and venturesome spirit. If you fail in this way, the hit that you take to your reputation is greatly outweighed by what you learn. Repeated failure will toughen your spirit and show you with absolute clarity how things must be done.

All great leaders since Moses have known that a feared enemy must be crushed completely. (Sometimes they have learned this the hard way.) If one ember is left alight, no matter how dimly it smolders, a fire will eventually break out. More is lost through stopping halfway than through total annihilation: The enemy will recover, and will seek revenge. Crush him, not only in body but in spirit.

I didn't like writing just articles and things. So then I wandered around. I tried my hand at film and television and that was a worse fit because I don't really have a mind for that.

There is a tremendous problem in modern culture. We have become used to everything coming to us with tremendous speed and ease. It is a culture where discipline and patience is almost impossible to develop.

I think I can do whatever I want with fiction, but the more documentary it is, the better it will be because that's what I'm good at. I'm good at observing people's behavior and putting these unspoken things into movie contexts in ways that other people can sometimes miss.

We're selfish to some degree, that's not a criticism and it doesn't mean that we are all narcissists. But in any situation our minds naturally evolve to what's in it for me? How does this affect me? Can this benefit me? Can this harm me? Then we might move on from that and have a more altruistic point of view about things but that's almost always our initial response.
