I flew into Zurich, Switzerland this morning, and then traveled two hours to Davos to attend the World Economic Forum (WEF). On the way, I learned Davos is Europe’s highest-altitude city. It is a small and remote place with only around 13,000 residents and only one road in and out. The WEF is a five-day meeting where 2,500 of the world’s top business leaders, heads of state, and public figures get together to try to solve the problems confronting the other nearly 7 billion of us.

It is a remarkable concentration of some of the best minds in business, technology and politics – all together in one remote destination. I can tell you, despite its high-profile attendees, the forum isn’t official or formal. Former President Clinton is just "Bill" here in Davos. There are no titles, and there are no fancy restaurants. Most of the attendees hang out in the cafeteria hall.

To be clear, though, there are two meetings going on here. After the panels are completed, there are dozens of private gatherings where some of the real work gets done. If you have heard of the Global Health Initiative, you may also know that Kofi Annan launched it at the 2002 annual meeting. The mission was to take advantage of the public/private partnerships towards combating malaria, tuberculosis and HIV/AIDS. In 1989, North and South Korea spoke for the first time here at Davos.
