“People do it all the time--assume that they "know" what's going on in someone else's head. That's impossible. And to think it's possible is a mistake. A really big mistake. A life-ruining one if you're not careful.”

“But clever people all make one mistake. They all think everyone else is stupid. And everyone isn't stupid. They just take a bit more time, that's all.”

“People make mistakes, it's just part of life. But, it's what we do with those mistakes that matters. What matters is what we learn from the mistakes, not what the mistake is.”

“Thinking of someone else is what got me damned. It’s a mistake I don’t want to repeat. (Xypher)You know sometimes it’s by repeating our mistakes that we realize what went wrong the first time. Knowing that, we’re able to fix the mistake and move past it. (Acheron)”

“No brain at all, some of them [people], only grey fluff that's blown into their heads by mistake, and they don't Think.”

“I love you sons of bitches. You’re all I read any more. You're the only ones who’ll talk all about the really terrific changes going on, the only ones crazy enough to know that life is a space voyage, and not a short one, either, but one that’ll last for billions of years. You’re the only ones with guts enough to really care about the future, who really notice what machines do to us, what wars do to us, what cities do to us, what big, simple ideas do to us, what tremendous misunderstanding, mistakes, accidents, catastrophes do to us. You're the only ones zany enough to agonize over time and distance without limit, over mysteries that will never die, over the fact that we are right now determining whether the space voyage for the next billion years or so is going to be Heaven or Hell.”
