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.

Look at the way celebrities and politicians are using Facebook already. When Ashton Kutcher posts a video, he gets hundreds of pieces of feedback. Maybe he doesn't have time to read them all or respond to them all, but he's getting good feedback and getting a good sense of how people are thinking about that and maybe can respond to some of it.

Building a mission and building a business go hand-in-hand. It is true that the primary thing that makes me excited about what we're doing is the mission, but I also think, from the very beginning, we've had this healthy understanding which is that we need to do both.

You can be so bad at so many things... and as long as you stay focused on how you're providing value to your users and customers, and you have something that is unique and valuable... you get through all that stuff.

What really motivates people at Facebook is building stuff that they're proud of.
