Show gratitude. Gratitude is a simple but powerful thing.

No matter how bad things are, you can always make things worse. At the same time, it is often within your power to make them better

Proper apologies have three parts: 1) What I did was wrong. 2) I feel badly that I hurt you. 3) How do I make this better?

Never lose the child-like wonder. It’s just too important. It’s what drives us. Help others.

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.

Be good at something. It makes you valuable.

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