Right now, America doesn't ask us to do anything besides pay taxes. We don't even have to vote. But as psychologists will tell you, when you have to sacrifice for something, you value it more. What about national service for young people? Everybody between 18 and 24 could spend a year or two working for this country in some capacity. It'd be an amazing thing. And it would mix this country racially, culturally, economically.

At 19, your brain hasn't finished wiring itself. So the first time you have a good friend die, most people don't go through that at 19. Soldiers do. They're facing life in this accelerated, compressed form, and a lot of times, they're not ready for it.

I decided to start a medical training program for freelancers, only freelancers. They're the ones who are doing most of the combat reporting. They're taking most of the risks. They're absorbing most of the casualties. And they're the most underserved and under-resourced of everyone in the entire news business.

If hardship brought out the worst in people, the human race wouldn't have survived. Right after 9/11, for instance, the murder rate actually went down in New York City. In World War II during the Blitz, the civilians of London were bombed almost every night for six months, but psychiatric admissions declined.

Who wants a life of ease? And who wants a life in the office that you hate, and who wants to play golf?

Here's an easy way to see if a war movie is being truthful: If you see an explosion on a faraway hillside and the sound of the explosion and the detonation of the bomb happen at the same time - if they're putting the sound and the vision together in the same moment - they're going toward our cultural understanding of war, not the reality of war.

I hope I get married one day.
