"The more you focus, the more that focus becomes a habit. So, willpower is like a muscle, right? It's this muscle that you can build up, and it gets tired, but the more you exercise it, the stronger it gets. The same is true of our ability to focus. The more you practice focusing, the easier focusing becomes."
"When you consider that the earth is almost entirely solar powered today and the fact that we're not a frozen ice ball at 4 degrees kelvin and it's just due to the sun. And the whole ecosystem is powered by the sun. There's just an itty bitty amount of energy that we need to do complicated human things. It's a tiny amount of energy compared to what the sun puts on the earth every day. And we just need to capture a little bit of that and turn it into electricity. So we have to try to accelerate that with innovation. And that's what SolarCity is about."
"I don't ever expect to be reunited with Carl. The great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief and precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting. Every single moment that we were alive and we were together was miraculous... We knew we were beneficiaries of chance. That pure chance could be so generous and so kind. That we could find each other, as Carl wrote so beautifully in Cosmos, in the vastness of space and the immensity of time... That is something which sustains me and it's much more meaningful. The way he treated me and the way I treated him, the way we took care of each other and our family, while he lived. That is so much more important than the idea I will see him someday. I don't think I'll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful."
"The U.S. does not have a policy of striking nations that use weapons of mass destruction automatically. If we had such a policy, one would wonder where the policy has been before now. Because the reality of the policy is, if a nation use weapons of mass destruction, we write that down and we put it in a folder. And if we need to go after that nation for some other reason in the future, we'll pull out that little folder and say, ' Well look at the list of abuses that this regime has been involved in.'
I mean, one of the things we used as a justification to go after Saddam Hussein was his use of chemical weapons, especially against his own people. We just didn't bring up that he had done that a decade before. And, oh yeah, with our passive agreement to that."
"This has always happened. We just finished a show on the Spanish-American War era, and Teddy Roosevelt is trying to tell people in the U.S. Congress who keep bringing up The Constitution, 'That might have been fine in the age of sail, but we live in the age of steam now. And all of a sudden Europe isn't that far away. And these oceans aren't protecting us as much as they used to.'
We've been dealing with that pretty much since minute one. So I think you can make that argument, 'We're in the age of drones now.' Either they're timeless and they're human rights and you're born with them, or as soon as things get dangerous enough, they're gone."
"If you want to know the scientific basis of atheism, you wanna talk to Richard Dawkins. If you want the historical and philosophical breakdown, you wanna talk to Sam Harris. If you want a modern day global feel of atheism, you talk to Christopher Hitchens. If you want a psychological breakdown of atheism, you talk to Daniel Dennett. If you want an atheist who dropped his cock in a blow-dryer, you talk to Penn Jillette."
"A long habit of not thinking a thing wrong, gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom. But the tumult soon subsides. Time makes more converts than reason."
