Earnestness is highly underestimated. It comes from the core, while hip is trying to impress you on the surface.

Advice is very easy to give, and even easier not to follow, so I don't fool with it.

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'll take an earnest person over a hip person every day, because hip is short-term, earnest is long term.

The brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something. Because the brick walls are there to stop the people who don’t want it badly enough. They’re there to stop the other people.

There's a lot of talk these days about giving children self-esteem. It's not something you can give; it's something they have to build. Coach Graham worked in a no-coddling zone. Self-esteem? He knew there was really only one way to teach kids how to develop it: You give them something they can't do, they work hard until they find they can do it, and you just keep repeating the process.

When you're frustrated with people, when they've made you angry, it just may be because you haven't given them enough time.
