The quick shall inherit the earth.

Fast is better than slow.

While slow is adding unnecessary embellishments, fast is out in the world.

And that means fast can learn from experience while slow can only theroize.

Those who ship quickly can improve quickly.

So fast doesn't just win the race. It gets a head start for the next one.

6 months or 30 years

There is no point in having a 5-year plan in this industry.

With each step forward, the landscape you are walking on changes. So we have a pretty good idea of where we want to be in six months, and where we want to be in 30 years. And every six months, we take another look at where we want to be in 30 years to plan out the next six months.

It is a little bit shortlighted and a little bit not.

Greatness and comfort rarely coexist.

If we don't create the thing that kills Facebook, someine else will.

"Embracing change" isn't enough. It has to be so hardwired into who we are that even talking about it seems redundant. The interest is not a friendly place.

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.

Changing how people communicate will always change the world.

Changing how ideas spread changes how society functions, changes how people speak, changes how people live, changes how people tell stories, changes how people fall in love, changes who people consider friends, changes who people consider strangers, changes what being alone means.

When you don't realize what you can't do, you can do some pretty cool stuff.

We don't build services to make money; we make money to build better services.

That means each Facebook engineer is responsible for approximately 1000000 people using Facebook.

Remember people don't use Facebook because they like us.

They use it because they like their friends.

Hacking can be playful---as long as it works.

Historically, those who controlled the media controlled the message. If you are the only one with a printing press, you control what people read. Same with radio. Same with TV.

But what happens when everyone can put their message in front of a lot of people? When the playing field is level? When everyone has a printing press, the ones with the best ideas are the ones people listen to. Influence can no longer be owned. It must be earned.
