One of the things that amazes me about Twitter is the way it utterly eradicates artificial barriers to communication. Things like status, geopolitics and so on keep people from talking to one another. Those go away in Twitter. You see exchanges that would never happen anywhere else.

The racing bug is never going to go away. It's like the Mafia.

I like things that are just about to go. Everything's leaving. Death is never far away from me. When you make something, death can't help but be in it.

The way you build trust with your team is around super-clear communication in that instant when they say, 'I will be sad if you don't do X.' You have to say, 'We're not going to do X, and here's why, and believe me, you'll be much sadder later if I let you go do it and you spend a bunch of time on it and nothing ever happens.'

I mean the terrorists are - are like a pimple, like a boil. They'll go away.

History rarely repeats itself, but its echoes never go away.
