Just take terrorism, for example. We have a team of more than 200 people working on counterterrorism. I mean, that’s pretty intense. That’s not like what people think about what Facebook is.

What really motivates people at Facebook is building something that’s worthwhile, that they’re going to be proud to show to friends and family.

I just think people have a lot of fiction. But, you know, I mean, the real story of Facebook is just that we’ve worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded.

Most businesses think that product is the most important thing, but without great leadership, mission and a team that deliver results at a high level, even the best product won’t make a company successful.

I failed to make the chess team because of my height.

Think about what people are doing on Facebook today. They’re keeping up with their friends and family, but they’re also building an image and identity for themselves, which in a sense is their brand. They’re connecting with the audience that they want to connect to. It’s almost a disadvantage if you’re not on it now.

This is our commitment to users and the people who use our service, is that Facebook’s a free service. It’s free now. It will always be free. We make money through having advertisements and things like that.

One of my big regrets is that Facebook hasn’t had a major chance to shape the mobile operating system ecosystem.

A lot of times, I run a thought experiment: ‚If I were not at Facebook, what would I be doing to make the world more open?‘

The thing that’s been really surprising about the evolution of Facebook is – I think then, and I think now – that if we didn’t do this, someone else would have done it.

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.

What I think we need to do is pass a bill that says number one, you own your data. Number two, you can license it to Facebook but the licensing has to be knowing, it has to be willful.

When we are thinking about stuff like embeds, we are not thinking about how we are competing with YouTube. We are thinking about how are we going to make it more useful for people to share stuff on Facebook.

It used to be the case, like you’d switch jobs, and then maybe you wouldn’t keep in touch with all the people that you knew from that old job, just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.

The main Facebook usage is so big. About 20 percent of the time people spend on their phone is on Facebook.

Facebook is inherently viral. There are lots of sites that include a contact importer, and for lots of them it doesn’t really make sense. For Facebook it fits so well. It wasn’t until a few years in that we started building some tools that made it easier to import friends to the site. That was a huge thing that spiked growth.

Working with a lot of people at the same time is a task. I really like making stuff and getting stuff done. One of the things I really liked about Facebook was that I could always move so quickly. I wrote the original application in, like, nine days at the end of January.

On engagement, we’re already seeing that mobile users are more likely to be daily active users than desktop users. They’re more likely to use Facebook six or seven days of the week.

No one has done a study on this, as far as I can tell, but I think Facebook might be the first place where a large number of people have come out. We didn’t create that – society was generally ready for that. I think this is just part of the general trend that we talked about, about society being more open, and I think that’s good.

I was a good football player, and I had a chance to play with some great players.

Facebook is in a very different place than Apple, Google, Amazon, Samsung, and Microsoft. We are trying to build a community.

People love photos. Photos originally weren’t that big a part of the idea for Facebook, but we just found that people really like them, so we built out this functionality.

After launching the first version of Facebook for a few thousand users, we would discuss how this should be built for the world. It wasn’t even a thought that maybe it could be us. We always thought it would be someone else doing it.

March is a month without mercy for rabid basketball fans. There is no such thing as a ‚gentleman gambler‘ when the Big Dance rolls around. All sheep will be fleeced, all fools will be punished severely… There are no Rules when the deal goes down in the final weeks of March. Even your good friends will turn into monsters.

When I started Facebook from my dorm room in 2004, the idea that my roommates and I talked about all the time was a world that was more open.

I see fighters make funny videos about me and stick them on Facebook and get 20 likes. When I make a video, I sell it to Fox and make seven figures. That’s the difference.

I actually don’t read most of the coverage about Facebook. I try to learn from getting input from people who use our services directly more than from pundits.

I think Facebook is an online directory for colleges… If I want to get information about you, I just go to TheFacebook, type in your name, and it hopefully pulls up all the information I’d care to know about you.

I hope that Facebook and other Internet technologies were able to help people, just like we hope that we help them communicate and organize and do whatever they want to every single day, but I don’t pretend that if Facebook didn’t exist, that this wouldn’t even be possible. Of course, it would have.

We should pass the U.N.’s Comprehensive Convention on International Terrorism. At least it will clearly establish whom you view as a terrorist and whom you don’t. We need to delink terrorism from religion – to isolate terrorists who use this interchange of arguments between terrorism and religion.

The thing that we are trying to do at facebook, is just help people connect and communicate more efficiently.

The bottom line is, when people are crystal clear about the most important priorities of the organization and team they work with and prioritized their work around those top priorities, not only are they many times more productive, they discover they have the time they need to have a whole life.

This younger generation that’s around, that’s tweeting, Facebooking and Vine-ing, the fans appreciate that because they feel like they can get to you.

We’re a community of a billion-plus people, and the best-selling phones – apart from the iPhone – can sell 10, 20 million. If we did build a phone, we’d only reach 1 or 2 percent of our users. That doesn’t do anything awesome for us. We wanted to turn as many phones as possible into ‚Facebook phones.‘ That’s what Facebook Home is.

We’re at a point now where we’ve built AI tools to detect when terrorists are trying to spread content, and 99 percent of the terrorist content that we take down, our systems flag before any human sees them or flags them for us.

I’ve been a lot more into Facebook and Twitter and Instagram, which was a bit complicated for me to understand the language of each social media, because they all talk in different ways. It’s a nice way for me to tell people I appreciate them, which I forget to do sometimes.

Innovation has nothing to do with how many R & D dollars you have. When Apple came up with the Mac, IBM was spending at least 100 times more on R & D. It’s not about money. It’s about the people you have, how you’re led, and how much you get it.

There is only one ‚retirement plan‘ for terrorists.

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

Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn’t do with anything else, we just have to do it.

I have a good team. It’s good to have a good team.

People at Facebook are fairly used to the press being nice to us or not nice to us.

At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people’s capacity to build and maintain relationships.

MySpace is my wife… Facebook is my mistress.

Once I found this possibility to use Twitter and Facebook and my blog to connect to my readers, I’m going to use it, to connect to them and to share thoughts that I cannot use in the book.

I was told that someone on Facebook said something ‚horrible‘ about me. Who cares? At least they’re watching the show.

People invest in businesses that they believe have the leadership, mission and team to grow and operate profitably.

All I can tell them is pick a good one and sock it. I get back to the dugout and they ask me what it was I hit and I tell them I don’t know except it looked good.

It’s not that every single thing that happens on Facebook is gonna be good. This is humanity. People use tools for good and bad, but I think that we have a clear responsibility to make sure that the good is amplified and to do everything we can to mitigate the bad.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that’s something we’re proud of.

The real story of Facebook is just that we’ve worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded.

My goal was never to make Facebook cool. I am not a cool person.

Facebook was not originally created to be a company. It was built to accomplish a social mission – to make the world more open and connected.

We started off as this platform inside Facebook; and we were pretty clear from the beginning that that wasn’t where it was going to end up. A lot of people saw it and asked, ‚Why is Facebook trying to get all these applications inside Facebook when the web is clearly the platform?‘ And we actually agreed with that.

I hate writing about personal stuff. I don’t have a Facebook page. I don’t use my Twitter account. I am familiar with both, but I don’t use them.

There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook. One such program was this program called Match. People could enter the different courses that they were taking, and see what other courses would be correlated with the courses they are taking.

You have to believe in your process. You have to believe in the things that you are doing to help the team win. I think you have to take the good with the bad.

We talk about this concept of openness and transparency as the high-level ideal that we’re moving towards at Facebook. The way that we get there is by empowering people to share and connect. The combination of those two things leads the world to become more open.

I’ve been doing comedy longer than I haven’t been doing comedy, as I was performing for three years before I even got on ‚The Tonight Show.‘ There’s truly nothing like it; it’s intense and exhilarating, even though it looks so casual.

When Facebook was getting started, nothing used real identity – everything was anonymous or pseudonymous – and I thought that real identity should play a bigger part than it did.

That pleasure which is at once the most pure, the most elevating and the most intense, is derived, I maintain, from the contemplation of the beautiful.
