When you're screwing up and nobody says anything to you anymore, that means they've given up on you.

The questions are always more important than the answers.

Whatever news we get about the scans, I’m not going to die when we hear it. I won’t die the next day, or the day after that, or the day after that. So today, right now, well this is a wonderful day. And I want you to know how much I’m enjoying it.” I thought about that, and about Jai’s smile. I knew then. That’s the way the rest of my life would need to be lived.

I understand the arguments about how the billions of dollars spent to put men on the moon could have been used to fight poverty and hunger on Earth. But, look, I'm a scientist who sees inspiration as the ultimate tool for doing good. When you use money to fight poverty, it can be of great value, but too often, you're working at the margins. When you're putting people on the moon, you're inspiring all of us to achieve the maximum of human potential, which is how our greatest problems will eventually be solved.
