Sometimes freedom from normal rules is what gives you competitive advantage.

Even by Silicon Valley standards, PayPal's vision was massively ambitious.

I'm a little unusual: I'm a six-person-or-less extrovert.

For Trump, the reasons to release his tax returns have always been compelling. Doing so would show the American people he doesn't just talk about accountability and transparency but also walks the walk.

I usually allocate time each week to work on topics outside of the normal workflow. These topics can be multi-year strategies for work, theories of how the world is changing, or just something refreshingly different or new.

I've long believed that if you're not embarrassed by your first product release, you've released too late.

If you can get better at your job, you should be an active member of LinkedIn, because LinkedIn should be connecting you to the information, insights and people to be more effective.

Hard work isn't enough. And more work is never the real answer. The sort of grit you need to scale a business is less reliant on brute force. It's actually one part determination, one part ingenuity, and one part laziness.

What makes the meaning of life is people, so you try to be good to people immediately around you and in your broader community. So a lot of my projects are about how I can affect the world in the hundreds of millions.

To have your parents get divorced at a young age, there's a lot of turbulence. We all grew up together, in some way. It was not idyllic. It was intense, vibrant, sometimes oppressive. I felt I was very much in a world of my own. I didn't meld much in school. I was kind of a loner.

The opportunity to build an enduring product far outweighs the cost of alienating a few users along the way. And the sooner you internalize that trade-off, the faster you'll move along the path to scale.

In crisis times, it's actually not more difficult to motivate your staff, because everyone gets much more focused on how they control their own economic destiny.

If you could train an AI to be a Buddhist, it would probably be pretty good.

'Founder' is a state of mind, not a job description, and if done right, even CEOs who join after day 1 can become founders.

I won a Marshall scholarship to read philosophy at Oxford, and what I most wanted to do was strengthen public intellectual culture - I'd write books and essays to help us figure out who we wanted to be.

Jeremy Stoppelman started Yelp. Max Levchin started Slide. I started LinkedIn. It was a mininova explosion of folks jumping out to doing other entrepreneurial activities.

We want to be inclusive. We want to have our shareholders, our employees, our customers, whether they are Democrat, Republican, Green or Libertarian, to feel comfortable with how we're doing business. And so that tends to be apolitical. People say, 'No, no, I just simply shouldn't get involved in politics.'

There's a lot of people in the world that would love to trade places with American citizens, and we are very fortunate to be here.

One of the metaphors that I use for start-ups is, you throw yourself off a cliff and assemble your airplane on the way down. If you don't solve the right problem at the right time, that's the end. Mortality puts priorities into sharp focus.

Relatively few people should start companies.

Social networks do best when they tap into one of the seven deadly sins. Facebook is ego. Zynga is sloth. LinkedIn is greed.

As an entrepreneur and investor, I prioritize construction and collaboration. Whether it's a five-person start-up or a global giant, the companies that are most productive are the ones whose employees operate with a shared sense of purpose and a clear set of policies for responding to changing conditions and new opportunities.

Some people mistake grit for sheer persistence - charging up the same hill again and again. But that's not quite what I mean by the word 'grit.' You want to minimize friction and find the most effective, most efficient way forward. You might actually have more grit if you treat your energy as a precious commodity.

Death Row inmates are almost twice as expensive to house each year as other inmates. Death penalty trials are much costlier than trials where execution is not a potential punishment and consume more time from judges, public defenders, and other legal personnel.
