I always knew I wanted to write, but I didn't know that I would want to do investigative reporting - in part because it seemed so ill-suited for my personality, or I thought it was ill-suited for my personality, insofar as I'm not very aggressive, and I'm not confrontational.

One thing I've discovered is that if you remain in contact with people, if you build longitudinal relationships, if you invest in sources who seem at first like they're uncomfortable or unwilling to talk, if you keep in touch with them, a year later that might yield something much more powerful.

I try to come to my reporting as a real, whole person, not an automaton. And it's always one of the strange discomforts of the job, that you're in this very intense moment in someone's life - you're engaging with them nonstop - and then suddenly your piece is out and that's done. It always reminds me that the journalist's job isn't to be someone's friend, or their psychologist, or anything other than what we actually are. And at the end of the day, that can definitely seem like such a strange, extractive relationship.

I think most of us, as writers, have had experiences where you get edited and it doesn't feel like your voice at all. And so it's been nice to go through the experience of having a lot wind up on the cutting-room floor, and yet still feel that your voice is being - not purified, but made more yourself. I think that's a very rare thing.

So much of our cultural representation of what an investigative journalist looks like, in movies and pop culture, is about this really testosterone-filled dude screaming, "Give me what you got!" I didn't see myself as someone who would be good at or comfortable with that.

When everyone's focused on the conventional parts of war - doing infantry imbeds or chasing IEDs - you look at the thing that seems not that interesting to people, like the circumstances of logistics workers cooking the troops' food or cleaning their latrines.

The tremendous challenge of narrative journalism about subjects that are underreported is, how do you make people care about something they think they already know about, or think they don't need to know about?
