I've actually not read any books on time management.

The idea of lying on a beach as my main thing just sounds like the worst. It sounds horrible to me. I would go bonkers. I would have to be on serious drugs. I'd be super-duper bored. I like high intensity.

It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

Facebook is quite entrenched and has a network effect. It's hard to break into a network once it's formed.

There are some important differences between me and Tony Stark, like I have five kids, so I spend more time going to Disneyland than parties.

I think the high-tech industry is used to developing new things very quickly. It's the Silicon Valley way of doing business: You either move very quickly and you work hard to improve your product technology, or you get destroyed by some other company.

Starting and growing a business is as much about the innovation, drive and determination of the people who do it as it is about the product they sell.
