Once I was condemned to three months' absolute silence. As I could not speak, I wrote a book.

UNICEF has made the most rewarding thing that I have ever done in my life.

I always try to see things with children's eyes. Are they happy? Sad? What do they need? Everywhere I went, I realized that children are society's victims ... We have a duty to speak to political leaders, to influence people to give these children a better future.

I do believe that if you haven't learnt about sadness, you cannot appreciate happiness.

When you want something very dearly, you make the time.

Wherever you turn, there is always something wrong with the politicians. They have everything they need to save the world, and they don't save it.

If I was sad or afraid, I would sit in a corner and sing. If I was happy I would jump into the middle of the room and sing. It was how I expressed my emotions.
