Now, as smartphones are coming up, there are all kinds of apps that will start to be developed that will help women.

If we don't empower women, we don't allow them to unlock the potential of themselves and their children.

I am Catholic, I was raised Catholic, I am a practicing Catholic. But I say we need to agree to disagree. We have a shared mission around poverty, and I focus on that, because we do a lot with the Catholic Church around poverty alleviation. I'm always looking for: what is the common thread?

[Bill Gates] wanted me to stay working at Microsoft, but I didn't think he could be CEO and we could have the family life that we both had growing up, which is what we envisioned. I knew I would go back to work at some point later to some profession. I just didn't know what.

Bill [Gates] and I believe philanthropy can only be effective if it starts things and proves whether they actually work or not. That's the place that governments often don't want to, or can't, work.
