Be who you are and say what you feel, because those who mind don't matter, and those who matter don't mind.

What I mean is that if you really want to understand something, the best way is to try and explain it to someone else. That forces you to sort it out in your own mind.

Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws.

The Hingefreel people of Arkintoofle Minor did try to build spaceships that were powered by bad news but they didn't work particularly well and were so extremely unwelcome whenever they arrived anywhere that there wasn't really any point in being there.

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.

There is another theory which states that this has already happened.

A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

The ships hung in the sky in much the same way that bricks don't.

I love deadlines. I love the whooshing noise they make as they go by.

I may not have gone where I intended to go, but I think I have ended up where I needed to be.

Anything works if you can make it work.

You are never dedicated to something you have complete confidence in. No one is fanatically shouting that the sun is going to rise tomorrow. They know it's going to rise tomorrow. When people are fanatically dedicated to political or religious faiths or any other kinds of dogmas or goals, it's always because these dogmas or goals are in doubt.

“In a car you're always in a compartment, and because you're used to it you don't realize that through that car window everything you see is just more TV. You're a passive observer and it is all moving by you boringly in a frame.

On a cycle the frame is gone. You're completely in contact with it all. You're in the scene, not just watching it anymore, and the sense of presence is overwhelming.”

The truth knocks on the door and you say, "Go away, I'm looking for the truth," and so it goes away. Puzzling.

You look at where you're going and where you are and it never makes sense, but then you look back at where you've been and a pattern seems to emerge.
