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

I hope I get married one day.

People who do really dangerous tasks can't afford to sit around and discuss the merits of what they're doing.

Society can give its young men almost any job and they'll figure how to do it. They'll suffer for it and die for it and watch their friends die for it, but in the end, it will get done. That only means that society should be careful about what it asks for. ... Soldiers themselves are reluctant to evaluate the costs of war, but someone must. That evaluation, ongoing and unadulterated by politics, may be the one thing a country absolutely owes the soldiers who defend its borders.

It's fun to have money, but the more money I get, the less interesting it becomes. If you don't have very much, you have to think about it. If you are starving, you become interested in food. If you are struggling to pay the bills, money becomes tragically important.

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.

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.
