Sometimes all you have to do is ask, and it can lead to all your dreams coming true.

I'm dying, and I'm having fun.

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.

If I could only give three words of advice, they would be, 'Tell the truth.' If I got three more words, I'd add: 'All the time.'

Anybody can get chewed out. It's the rare person who says, oh my god, you were right. As opposed to, no wait, the reason is... We've all heard that

I'm sorry. It's my fault. How do I make it right?

Read at least one book a month. This is self-serving, obviously. It's a proven fact that people who read buy more books than people who don't read. In truth, I wish you'd read ten books a month, or at least buy that many.
