The biggest risk is not taking any risk... In a world that changing really quickly, the only strategy that is guaranteed to fail is not taking risks.

Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.

Facebook is all about information and helping people share it.

The biggest risk is not taking any risk.

People can be really smart or have skills that are directly applicable, but if they don't really believe in it, then they are not going to really work hard.

The world isn't set up equally, and the first billion people using Facebook have way more money than the rest of the world combined.

In a recent survive of Millennials around the world asking what most defines our identity, the most popular wasn't nationality, ethnicity or religion. It was "citizen of the world." That's a big deal. Every generation expands the circle of people we consider one of us. And in our generation, that now includes the whole world. This is the struggle of our time. The forces of freedom, openness, and global community against the forces of authoritarianism, isolationism, and nationalism - forces for the flow of knowledge, trade, and immigration, against those who would slow them down.
