I would like to call on young people to commit themselves to activities that contribute toward achieving their long-term dreams. They have the energy and creativity to shape a sustainable future. To the young people I say, you are a gift to your communities and indeed the world. You are our hope and our future.

That's the way I do things when I want to celebrate, I always plant a tree.

It's very important to remain optimistic and to see the silver lining in everything you do. Because no matter how sometimes things look difficult, and look like there is no hope, there is always a small glimmering of silver lining that is in everything, and I always look for that, and hang on that, and before I know it, another day comes and is gone.

There will always be people who think that you have ambitions.

I have always felt that perhaps women have sometimes almost embraced the same values as men, and the same character as men, because they are in the men's world, and they are trying to fit into a system that men have created. And maybe in truth when there is a critical mass of women who play that role in governments, then we will see whether women can really manage power in a way that is less destructive than the way that men have used power.

In a few decades, the relationship between the environment, resources and conflict may seem almost as obvious as the connection we see today between human rights, democracy and peace.

I learned in America a long time ago, the three R's, the principle of three R's - reuse, reduce, recycle. And as I say those words, there are so many things individually we can do to reduce - we don't need to consume as much as we are consuming. Reduce. And by reusing, we can reuse a lot of things we just throw into the dumpsite. And reduce the production. The more we reuse, the more we can reduce.
