If you come face to face with some really challenging situations and tragic circumstances - you are going in there with a purpose. You are not going in there as a tourist. You're not going there just to merely observe. You have a purpose, and your purpose is to tell that story, to share that story for the bigger benefit of millions of other people. Your purpose is to create that bridge so you can give that story the dignity and the focus that it deserves, and you can become a part of the amplification that needs to be there.

I'm not a Christian, but I think the Christian message is a good one.

I don't take myself as seriously as some people think, and I'd hate anyone to think I was preaching. That's the last thing I want.

I was perceiving myself as good as a man or equal to a man and as powerful and I wanted to look ambiguous because I thought that was a very interesting statement to make through the media. And it certainly did cause quite a few ripples and interest and shock waves.

I have a calling in my soul, if you like, to try to make my life in some way worthwhile. What is the value of my existence?

In the States, the HIV transmission from mother to child is almost completely preventable - the only mothers who really do transmit it are the ones who don't come in for care. If a mother in the United States or in Europe or in the UK comes to care and gets her medicines, she will have an HIV negative baby. Most people don't know that.

As a mother, you have that impulse to wish that no child should ever be hurt, or abused, or go hungry, or not have opportunities in life.
