The point of Facebook isn't the features, it's the people.

Move fast and break things. Unless you are breaking stuff, you are not moving fast enough.

When you want to change things, you can't please everyone. If you do please everyone, you aren't making enough progress.

We should have a society that measures progress not just by economic metrics like GDP, but by how many of us have a role we find the meaningful. We should explore ideas like universal basic income to make sure everyone has a cushion to try new ideas.

When I'm introspective about the last few years I think the biggest mistake that we made, as a company, is betting too much on HTML5 as opposed to native... because it just wasn't there. And it's not that HTML5 is bad. I'm actually, on long-term, really excited about it. One of the things that's interesting is we actually have more people on a daily basis using mobile Web Facebook than we have using our iOS or Android apps combined. So mobile Web is a big thing for us.

Facebook is really about communicating and telling stories... We think that people can really help spread awareness of organ donation and that they want to participate in this to their friends. And that can be a big part of helping solve the crisis that's out there.

There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook.
