“Some people don’t like change, but you need to embrace change if the alternative is disaster.”

It is a mistake to hire huge numbers of people to get a complicated job done.

The extension of life beyond Earth is the most important thing we can do as a species.

Most people can learn a lot more than they think they can. They sell themselves short without trying.

Give people their freedom back!

I hate writing about personal stuff. I don’t have a Facebook page. I don’t use my Twitter account. I am familiar with both, but I don’t use them.

The only reason I was able to accomplish things is the great people willing to work with me.

My mentality is that of a samurai. I would rather commit seppuku than fail.

I’ve actually not read any books on time management.

Persistence is very important. You should not give up unless you are forced to give up.

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

For my part, I will never give up, and I mean never.

When I was in college, I wanted to be involved in things that would change the world.

It’s OK to have your eggs in one basket as long as you control what happens to that basket.

I think life on Earth must be about more than just solving problems. It’s got to be something inspiring, even if it is vicarious.

Tesla is here to stay and keep fighting for the electric car revolution.

You could warm Mars up, over time, with greenhouse gases.

You realize as a director that when you are cutting a film, you want to have alternatives. You need color and choices. You don’t want four takes that are identical.

To me, growing old is great. It’s the very best thing – considering the alternative.

I don’t think we have any alternative other than remaining optimistic. Optimism is an absolute necessity, even if it’s only optimism of the will, as Gramsci said, and pessimism of the intellect.

There is no alternative to success. So stop thinking you should already be there.

The clear problem of the outlawing of insult is that too many things can be interpreted as such. Criticism, ridicule, sarcasm, merely stating an alternative point of view to the orthodoxy, can be interpreted as insult.

Government “planning” is not an alternative to chaos. It is a pre-emption of other people’s plans.

When people are presented with the alternatives of hating themselves for their failure or hating others for their success, they seldom choose to hate themselves.
