There's so much stigma around HIV/AIDS. It's a challenging issue, and the people that already have been tested and know their status find it very, very hard to disclose their status, to live with that virus, and to even seek out the kind of information they need. This experience of going to South Africa a decade ago really woke me up to the scale of the HIV/AIDS pandemic in sub-Saharan Africa, how it was affecting women and their children. I haven't been able to walk away from it.

Please don't ask me for the actual answer to anything, because I don't have it. Because all I do is look at stuff and ask questions. What can I say? I just think the world's barking mad. Look, I'm not an expert. I'm just an ordinary person.

The contrast of the world that we live in and the world that is here in Aspen and the world inhabited by women who have no resources, little or no, very few resources - huge disparity.

When you're that successful, things have a momentum, and at a certain point you can't really tell whether you have created the momentum or it's creating you.

I grew up in a middle class household with parents, went to good schools, and never feared for anything, never wanted for anything that was really important. For all of us living in this world, all of us who have the resources, for us to not dedicate ourselves to giving something back, is to leave the world a lesser place.

There was a time when I looked to other people for recognition, because I didn't have enough confidence to trust my own judgment. Now I'm not looking for reassurance, because I realize how fickle people are. My own strength is the best I can have.

Just having medicine isn't equivalent to medical care. You need the health systems, you need to create the social framework so that people feel safe.
