In a world that's changing so quickly, you're guaranteed to fail if you don't take any risks.

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.

Facebook is inherently viral.

While we generally believe in free speech and giving everyone as much ability to speak as possible, in practice there are lots of barriers to that, whether it's legal restrictions, technological restrictions or you can't share what you want if you don't have access to the internet.

There are social restrictions where someone could be suppressing someone else's freedom to express themselves.

People think innovation is just having a good idea but a lot of it is just moving quickly and trying a lot of things.

Move fast, take risks, it's okay to try big things you're better off trying something and having it not work and learning from that than having not done anything at all.
