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

One interesting thing I found was that if you take an affluent modern society and collapse it during a crisis, like a war or a natural disaster, people begin relating in a more ancient, organic way. They're functioning in small interdependent groups and putting others first. And another irony is that even in terrible times, cooperating makes people feel good.

The most profound question is, "What would I risk dying for?" The natural answer is "for my family." But for most of history, we didn't live in families. We lived in small communities that gave us our sense of safety and place in the world, so the natural answer would be "for my people." The blessing and the tragedy of modern life is that we don't need our community to survive anymore. When we lose that idea, we lose a sense of who we are.

The attacks of 9/11 came out of Afghanistan. It was a failed state, a rogue nation. That's why al Qaeda was there in the first place.

The only thing that makes battle psychologically tolerable is the brotherhood among soldiers. You need each other to get by.

The Army might screw you and your girlfriend might dump you and the enemy might kill you, but the shared commitment to safeguard one another’s lives is unnegotiable and only deepens with time. The willingness to die for another person is a form of love that even religions fail to inspire, and the experience of it changes a person profoundly.

The coward’s fear of death stems in large part from his incapacity to love anything but his own body. The inability to participate in others’ lives stands in the way of his developing any inner resources sufficient to overcome the terror of death. — J. Glenn Gary, The Warriors
