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.

I'm a professor - there should be some lessons learned - and how you can use the stuff you hear today to enable your dreams or enable the dreams of others. And as you get older you may find that enabling-the-dreams-of-others thing is even more fun.

Being successful doesn't make you manage your time well. Managing your time well makes you successful!

It's not how hard you hit. It's how hard you get hit... and keep moving forward.

Never lose the childlike wonder. Show gratitude... Don't complain; just work harder... Never give up.

We need to make sure our students are exerting themselves. We need to praise them when they deserve it and to tell them honestly when they have it in them to work harder.
