Bill Gates believes young entrepreneurs are Africa’s biggest strength.  Gates, billionaire and former CEO of Microsoft, “believes countries throughout Africa can obtain economic prosperity and fairly distributed wealth but only by mobilizing the region’s young entrepreneurs. He shared his optimistic vision as he delivered the Nelson Mandela Annual Lecture at South Africa’s University of Pretoria over the weekend. Gates said that the dynamism of youth has the power to change the world, noting that Steve Jobs, Mark Zuckerberg, and he himself all began their entrepreneurial journeys before turning 22.”
