It can be very dangerous to see things from somebody else's point of view without the proper training.

Bypasses are devices that allow some people to dash from point A to point B very fast while other people dash from point B to point A very fast. People living at point C, being a point directly in between, are often given to wonder what's so great about point A that so many people from point B are so keen to get there and what's so great about point B that so many people from point A are so keen to get there. They often wish that people would just once and for all work out where the hell they wanted to be.

This man is the bee's knees, Arthur, he is the wasp's nipples. He is, I would go so far as to say, the entire set of erogenous zones of every major flying insect of the Western world.

I don't really have any advice, other than to say it's the most appallingly difficult thing I've ever tried to do and I wish I had a better idea of how to do it. In my experience what you end up with is the by-product of your failure to achieve what you set out to do. It may turn out OK, but it wasn't what you meant and you've no idea how you got there.

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 mind. And the more slow and dim-witted your pupil, the more you have to break things down into more and more simple ideas. And that's really the essence of programming. By the time you've sorted out a complicated idea into little steps that even a stupid machine can deal with, you've learned something about it yourself... The teacher usually learns more than the pupils. Isn't that true?

We are stuck with technology when what we really want is just stuff that works.

There's always a moment when you start to fall out of love, whether it's with a person or an idea or a cause, even if it's one you only narrate to yourself years after the event: a tiny thing, a wrong word, a false note, which means that things can never be quite the same again.
