There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future. The scale of the technology and infrastructure that must be built is unprecedented, and we believe this is the most important problem we can focus on.

I think as a company, if you can get two things right--having a clear direction on what you are trying to do and bringing in great people who can execute on the stuff--then you can do pretty well.

It occurred to me that building a company was the best way to align a group of people towards building something great. And its really... it's a good organizational structure where you can really reward people. If they're building something that's good, you can you work with partners and reward them if the product that you're developing work well. It's a good way to get the best people involved to build something very good.

In a lot of ways Berlin is a symbol for me of Facebook's mission: bringing people together, connecting people and breaking down boundaries.

Don't discount yourself, no matter what you're doing. Everyone has a unique perspective that they can bring to the world.

You grow more when you get more people's perspective.

If things aren’t breaking, then you’re not moving fast enough. People learn by making mistakes.
