You've got to close deals quickly, or else you'll miss out.

While, in general, life satisfaction goes up with wealth, beyond the safety net more and more wealth brings very radically diminishing returns on life satisfaction.

The short version is I'm just a total Apple fanboy. I started programming Apples in seventh grade.

IT is now reaching out to fuels and chemicals, energy and clean tech, rockets, all kinds of bizarre industries that formerly didn't face much competition.

I've actually come to respect the most irritatingly challenging people I've worked with as really valuable in improving group decision-making and what to do and what to invest in.

You have to build businesses for longer term.

Firms that claim domain focus are late movers.

Without disruptions, startups can't survive.

Every new industry has exuberance in advance of reality. The techies get carried away. There is a period of despair. Then the pendulum swings the other way, and people see the long term potential. It's like when the Internet bubble crashed.

We believe strongly that all meaningful change comes from entrepreneurs.

When a nanotech company matures and becomes a real business, it becomes something else. It becomes a biotech company or a cleantech company or a memory chip company. Nanotechnology has fueled the core innovations in electronics and energy.

I don't really care what the venture industry thinks.

If you think 20 years out and ask what's the most important company on the planet, it is not any company you could write down today. The most important company 20 years from now has not even been founded yet and doesn't have a name.

We definitely stand behind Theranos in the sense of, we are an investor, and we want them to succeed.

The commercial space industry is enormous and ripe for disruption.

Venture capital is a dynamic and people-driven business.

Rockets often spiral out of control if you put too much propellant in them.

Flourishing is everyone's birthright. I'm trying to break this hold that being smiley and cheery has on what people think the good life is.

A big part of green tech will be organisms that eat waste.

No politician has a 50-year horizon.

The concept of a 'job' is pretty recent. If you go back a few hundred years, everyone was either a slave or a serf, or living off slave or serf labor to pursue science or philosophy or art.

One very interesting framework for a company to succeed over time - beyond just business logic and analytics - is, do they have a reason why the best graduates in engineering programs will flock to them versus competitors?

My interest in space started early, but for many years, I could not find any space-related investments that really penciled-out for venture. That changed in 2009 when Elon Musk came to us with a big vision to explore Mars while producing rockets at a fraction of a price and making space accessible.

Lots of deals happen in situations that aren't 'pure work.'

The economies of the future are information.

If there isn't a business logic to get to marketability, the chance of an idea's importance in the world is very low.

Elon Musk wins you over with his elegant mastery of engineering, be it for the rocket or the car. But what blew my socks off was when our conversation veered way off topic. We started musing about whether it was possible we all lived in the matrix, and Musk still had deep knowledge.

If I want to make a product that is appealing to consumers, like a piece of clothing or a video game, that's fad driven. Some companies do it, and I don't know how they do it, but it's generally a bad place to invest.

Hotmail grew its base faster than any company I can think of.

When I was 11, I went to space camp at the Space Center in Texas, near where I grew up. There, I met video-game-industry pioneer Richard Garriott, better known to gamers everywhere as 'Ultima' creator Lord British.

I can't invest in areas of comfort.

I'd stay away from investments in a variety of sectors that are capital intensive. Anyone who says we need $100 million before we know if what we're doing makes sense and the customers want it - that's not going to work.

I do lament how many investors focus on all the short-term sugar buzz of some marginal improvement in something - nothing history books are ever going to be written about. In many cases, these are quick and easy ways to make money.

Being slick is not the right answer.

I believe that technology has the potential to change the fate of nations, industries and companies, as well as the context of our lives. I want to help build the companies that take the risks needed to make those kinds of real changes in the world.

Elon Musk is an incredibly prolific entrepreneur, having come up with, or been at the founding team of Tesla, SpaceX, SolarCity, PayPal, all different industries that seem to have nothing to do with each other.

Truly original thinkers tend not to be entrepreneurs who've spent 10 years at Cisco and can be trusted to know what they're doing. They tend to be 26 years old and highflying. They often have a very childlike mind, with some naivete.

SpaceX lowered the cost of going into space by 10x.

There are many good ideas out there that never get an audience.

By day, I'm a venture capitalist. On weekends, I love rockets.

We're impressed by people who don't know what can't be done.

I would say that nanotech's worth paying attention to no matter what your background because if you look far enough into the future, it'll impact just about any industry you can think of.

We only invest in businesses that reduce labor.

Hotmail went from zero to 12 million users with zero marketing steps. Not a penny was spent on sales and marketing, which was astounding. It showed us the power of the network effect.

Building and launching rockets has been a lifelong hobby that my son and I share. We regularly travel to Nevada's Black Rock Desert to launch rockets.

It is quite moving to hold a piece of Mars in your hands and to reflect on its incredible interplanetary journey, and the science that gives confidence as to the origin of this unusual rock.

One tech-related concern with religion is that it appears to be a positive feedback loop to the accelerating rich-poor gap, as the disenfranchised opt out of modernity.

Because of the rate of technology change, forecast horizons are shrinking.

As a geek, I take umbrage at the notion that chips are not sexy. But yes, robots, drones, satellites and self-driving cars are the kinds of things that excite me.
