You want to have a future where you’re expecting things to be better, not one where you’re expecting things to be worse.

You should be innovating so fast that you're invalidating your prior patents.

It is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer (two people who don't know something are no better than one), will tend to slow down progress, and will make the task incredibly expensive.

That's my lesson for taking a vacation: vacation will kill you.

The thing that's worth doing is trying to improve our understanding of the world and gain a better appreciation of the universe and not to worry too much about there being no meaning. And, you know, try and enjoy yourself. Because, actually, life's pretty good. It really is.

There's nothing - I've bought everything I want. I don't like yachts or anything; you know, I'm not a yacht person, and I've got pretty much the nicest plane I'd want to have.

Really, the only thing that makes sense is to strive for greater collective enlightenment.
