For us who are now in power, we need to be challenged to serve the people and ignore our own egos and personal interests so that we can really demonstrate to other African states that it is possible to share power without going to war.

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.

You can make a lot of speeches, but the real thing is when you dig a hole, plant a tree, give it water, and make it survive. That's what makes the difference

There is no reason why a company like Monsanto, for example, that is pushing GMOs, cannot go to Kenya, partner with the university, partner with the research institutions, and try to promote - in a responsible way - advanced techniques to help farmers. But this should be done in such a way that the farmers' livelihoods are not undermined because the government is irresponsible or careless, or because it is compromised.

The way in which we can promote peace, is by promoting sustainable management of our resources, equitable distribution of these resources, and that the only way you can actually do that, is that then you have to have a political, economic system that facilitates that. And then you get into the issues of human rights, justice, economic justice, social justice, and good governance or democratic governance. That's how it ties up.

Every one of us can make a contribution. And quite often we are looking for the big things and forget that, wherever we are, we can make a contribution. Sometimes I tell myself, I may only be planting a tree here, but just imagine what's happening if there are billions of people out there doing something. Just imagine the power of what we can do.

We think that diamonds are very important, gold is very important, all these minerals are very important. We call them precious minerals, but they are all forms of the soil. But that part of this mineral that is on top, like it is the skin of the earth, that is the most precious of the commons.
