As a war correspondent and a mother, I've learned to live in two different realities... but it's my choice. I choose to live in peace and witness war - to experience the worst in people but to remember the beauty.

I was undeterred by the danger of traveling as a single American woman through Taliban-governed land. I believed in the stories I wanted to tell, the stories I felt were underreported, and I was convinced that that belief would keep me alive.

Obviously I am a photographer and I believe in my medium: I do think that powerful photographs can force change. It doesn't take long to look and be engaged in a strong image whereas, with a story, you have to actually sit down and pause and be involved in it.

You have to believe 100 percent in what you're doing, that some picture or some thing we do is going to change the world in some tiny, minute way.

To me, it's so much about doing your homework, going into a situation, getting to know the subject, making them feel comfortable, getting intimate access, getting access to all different aspects of people's lives, so that I am essentially telling an entire story and not just a single one.

One day I am at home, watching dramatic images of Iraqi Yazidis fleeing for their lives being aired nonstop on 24-hour news channels. Days later, I am there, staring at tens of thousands of displaced Iraqis and feeling a 35-millimeter frame cannot capture the scope of devastation and heartbreak before me.

I've seen so many photographers rush to do books the minute they start shooting, but one great thing about photography is that the images don't go away, so the more I sit with these images, the more I learn which ones have had the most impact.

I remember the moment in which we were taken hostage in Libya, and we were asked to lie face down on the ground, and they started putting our arms behind our backs and started tying us up. And we were each begging for our lives because they were deciding whether to execute us, and they had guns to our heads.

Let's get one thing straight: I am not an adrenaline junkie. Just because you cover conflict doesn't mean you thrive on adrenaline. It means you have a purpose, and you feel it is very important for people back home to see what is happening on the front line, especially if we are sending American soldiers there.
