Work like hell. I mean you just have to put in 80 to 100 hour weeks every week. [This] improves the odds of success.

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.

What I'm trying to do is to maximise the probability of the future being better.

Don't be afraid of new arenas.

If we drive down the cost of transportation in space, we can do great things.
