We cannot change the cards we are dealt, just how we play the hand.

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. Give yourself permission to dream.

We keep what is valuable to us, what we cherish.

When you do something young enough and you train for it, it just becomes a part of you.

People lie for lots of reasons, often because it seems like a way to get what they want with less effort.

I feel like I'm waiting on something that isn't going to happen Don't complain; just work harder.

It's easy to be smart when you are parodying smart people.
