“It's dizzying to think how huge the world is, or to realize how tiny you are”

“I realized a long time ago, with a certain amazement, that no mattter how important something is in your life, no matter how huge it is, how much space it takes up in your heart and in your thoughts, unless you mention it to other people, they have no idea it exists.”

“I think it's possible to realize you love someone as deeply as you know how to love and not end up spending the rest of your life with him.”

“People think it must be fun to be a super genius, but they don't realize how hard it is to put up with all the idiots in the world.”

“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”

“All I'm trying to say is that if you're not willing to observe this, if you're just going to condemn it, you're never going to see it. It's there, whether you like it or not. This is stupid life-force we're dealing with here," he said. "Think how old it is, Jim. Think how huge it is. Understanding it doesn't make any difference.”
