I understand the arguments about how the billions of dollars spent to put men on the moon could have 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. Fuel your kid's dreams, too. Once in a while, that might even mean letting them stay up past their bedtimes.
