I’ve been traveling to Africa regularly for more than two decades. Whenever I go, I’m struck by the unbridled optimism of the young people I see. Even in the face of some tough health and development challenges, they have a positive outlook about the future. They are ambitious. They think in innovative ways and are eager to learn the newest technologies. They are also willing to take risks. To see Africa through their eyes is to see a continent brimming with potential and opportunity.
