Arianna Huffington And Sheryl Sandberg On The Power Of Optimism

Joining Arianna Huffington at the World Economic Forum in Davos, Facebook COO Sheryl Sandberg discussed why she thinks a sense of optimism is central to reaching the solutions the world needs.

"There's so many real challenges in the world," said Sandberg. "Jobs challenges, connectivity challenges, challenges for democracy.
