That is why man can also never understand himself: For he is himself a timeless act; an act which he performs continuously, and there is no moment in which he might not perform it, as there would have to be to understand himself.

You can't understand human motivation. You can only understand your damned machines because you're a machine yourself, with skin on.

There will be things that I do that no one will be left to understand.

Besides which, she would never understand me because I like too many things and get all confused and hung-up running from one falling star to another till I drop. This is the night, what it does to you. I had nothing to offer anybody except my own confusion.

Get your hands to work, Selling, none of us can understand it.

It's really hard to explain, because it's a fucking prick of a job, you know? Particularly when you get successful with it.... People don't understand why your life suddenly changed when, hey, to them it's fucking ten bucks at the movies, it's over in a couple of hours. They dont understand the prep, they don't understand the real physical shit that you put yourself through. I mean, the last movie's an example— shoulder surgery partway through preparation. And it's a $100 million train, man, and I'm the fucking guy that drives the train. And I've got to get back on that train and make sure that this thing is completed.

If all I cared about was me, I could make a million. And that's what they will never understand.
