I believe education is the key. As an activist and a child of the developing world, I witnessed education's power to transform lives.

There's no better makeup than self-confidence.

I admire Madonna because she always did whatever she felt like doing. She went through some controversial periods when people rejected her, but she kept on reinventing herself.

In 2006 I was asked to sing at the World Cup in Germany, and in 2010 I was fortunate enough to be asked again.

I admire a person who, for the love of art, is able to take off their clothes in front of a camera. But I'm not capable, I'm too cowardly for that.

I've met dedicated people from all sectors of society who are committed to giving children the tools they need for a better future. I'm always impressed by the passionate young leaders I meet. As the pace of change accelerates, so do the challenges we face. However, the chances to solve them increase too.

I remember the first time I saw the 'Smells Like Teen Spirit' video. I will never forget that day. I just wanted to see Kurt Cobain's face. I had a feeling he was very cute. But, I couldn't see his face. When I finally did see him, he was even cuter than I imagined!
