It's not helpful if we spend every day dreading tomorrow ~Jai

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 work hard enough, there will be things I can do tomorrow that I can't do today.

Remember brick walls let us show our dedication. They are there to separate us from the people who don't really want to achieve their childhood dreams.

When you're screwing up and nobody says anything to you anymore, that means they've given up on you.

A lot of people want a shortcut. I find the best shortcut is the long way, which is basically two words: work hard.

Engineering isn't about perfect solutions; it's about doing the best you can with limited resources.
