It is extreme arrogance for one to think he is the only one who can govern his country and nobody else can do it. We're all human. After 10, 15 years you get tired, you run out of steam and ideas, you have to give a chance to somebody else. And whether you yourself are inclined to stay on, all those around you are pushing you to stay on for what they will gain. One has to have the strength of character to say the time has come to move on...unless you are a king.

You have made people listen. You have made people care, and you have taught us that whether we are poor or prosperous, we have only one world to share. You have taught young people that they do have the power to change the world.

One must also acknowledge that there are moments in an organisation's development when fresh blood and new vision are required, which may imply that an outsider may be better suited to the leadership role.

Obama saying Gaddafi must go. Putting it upfront like that... it's not very helpful.

I think the generational change is going to be so important for Africa that we really should encourage and push it as much as we can, because some of these younger men and women, who are men and women of their times, and are also connected to the rest of the world, wouldn't even know how to behave in the way some of the old leaders do.

If tolerance, respect and equity permeate family life, they will translate into values that shape societies, nations and the world.

If we can come up with innovations and train young people to take on new jobs, and if we can switch to clean energy, I think we have the capacity to build this world not dependent on fossil-fuel. I think it will happen, and it won't destroy economy.
