To paraphrase Einstein, you can't solve a problem using the same type of thinking that created it. When you consider this bit of wisdom alongside the scale of the problems we're facing around the world, it's clear that our current model of leadership sorely needs a refresh. Everywhere we look, we see leaders with high IQs making terrible decisions -- government shutdown, anyone? -- burned out and unable to tap into their own wisdom. That's why I'm here in Johannesburg to join a conversation among a group of 1,300 young leaders from all over the world who are every day solving problems in their communities. Being with them restores my faith in leadership. Together, we'll be highlighting examples from around the world of what is working when it comes to young people creating their own employment opportunities and extending opportunities to others.
