American government is not dominated by engineers, it is dominated by lawyers. Engineers are interested in substance and building things; lawyers are interested in process and rights and getting the ideology correctly blended. And so there is sort of no really concrete plan for the future.

I think markets are often not thinking on a long-time horizon, I think that our government structurally is doing even less so. When we have a government where we have people who are up for election at most once every six years for a U.S. senator, that's a time horizon that is much shorter than in a market that a company is looking at 10, 15, 20 years which is a time horizon over which a stock price is typically valued.

Great tech opportunities happen only once.

The developing world can just do things that are extensive or horizontal, that basically copy. The developed world needs to do things that are intensive or vertical, where we take our civilization to the next level.

The college kids should think hard about what they're doing. If you have a great idea for a company, there's no right time to start it, and it's often better to start it sooner rather than later. I went to Stanford undergrad and Stanford Law School, and if I had to do it over again, I might still do those things, but I wish I had asked the type of questions like, why I was doing it, was it just for the status and prestige, or was it because I was really interested in the substance of it.

The most successful businesses have an idea for the future that's very different from the present.

Brilliant thinking is rare, but courage is in even shorter supply than genius.
