Facebook is inherently viral.

I don't want to be in a situation where I have to leave some other commitment or worse I am rude and someone else has to support my stuff. I stopped coding for Facebook a while ago.

Providing the best photo sharing experience is one reason why so many people love Facebook and we knew it would be worth bringing these two companies together.

Find that thing you are super passionate about. A lot of founding principles of Facebook are that if people have access to more information and are more connected, it will make the world better; people will have more understanding, more empathy. That’s the guiding principle for me. On hard days, I really just step back, and that’s the thing that keeps me going.

I mean, we've built a lot of products that we think are good, and will help people share photos and share videos and write messages to each other. But it's really all about how people are spreading Facebook around the world in all these different countries. And that's what's so amazing about the scale that it's at today.

People developed planes first and then took care of flight safety. If people were focused on safety first, no one would ever have built a plane.

I generally think if you do good things for people in the world, that comes back and you benefit from it over time.
