Mark Zuckerberg

There are definitely elements of experience and stuff that someone who's my age wouldn't have. But there are also things that I can do that other people wouldn't necessarily be able to.

There are good examples of companies - Coca-Cola is one - that invested before there was a huge market in countries, and I think that ended up playing out to their benefit for decades to come.

If you go through some big corporate change, it's just not going to be the same. If we sold to Yahoo, they would have done something different; if you want to continue your vision of the company, then don't sell because there's inevitably going to be some change.

The companies that work are the ones that people really care about and have a vision for the world so do something you like.

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.

A lot of people are focused on taking over the world or doing the biggest thing and getting the most users. I think part of making a difference and doing something cool is focusing intensely.

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.

The biggest risk is not taking any risk... In a world that is changing really quickly, the only strategy that is guaranteed to fail is not taking risks.

I look at Google and think they have a strong academic culture. Elegant solutions to complex problems.

I started the site when I was 19. I didn't know much about business back then.

A frustration I have is that a lot of people increasingly seem to equate an advertising business model with somehow being out of alignment with your customers. I think it's the most ridiculous concept.

I feel that the best companies are started not because the founder wanted a company but because the founder wanted to change the world... If you decide you want to found a company, you maybe start to develop your first idea. And hire lots of workers.
