“Ginger: You know what the greatest tragedy is in the whole world?... It's all the people who never find out what it is they really want to do or what it is they're really good at. It's all the sons who become blacksmiths because their fathers were blacksmiths. It's all the people who could be really fantastic flute players who grow old and die without ever seeing a musical instrument, so they become bad plowmen instead. It's all the people with talents who never even find out. Maybe they are never even born in a time when it's even possible to find out. It's all the people who never get to know what it is that they can really be. It's all the wasted chances.”
― Terry Pratchett, Moving Pictures

“There are, it has been said, two types of people in the world. There are those who, when presented with a glass that is exactly half full, say: this glass is half full. And then there are those who say: this glass is half empty.
The world belongs, however, to those who can look at the glass and say: What's up with this glass? Excuse me? Excuse me? This is my glass? I don't think so. My glass was full! And it was a bigger glass! Who's been pinching my beer?
And at the other end of the bar the world is full of the other type of person, who has a broken glass, or a glass that has been carelessly knocked over (usually by one of the people calling for a larger glass) or who had no glass at all, because he was at the back of the crowd and had failed to catch the barman's eye. ”

“Real stupidity beats artificial intelligence every time.”

“He'd noticed that sex bore some resemblance to cookery: it fascinated people, they sometimes bought books full of complicated recipes and interesting pictures, and sometimes when they were really hungry they created vast banquets in their imagination - but at the end of the day they'd settle quite happily for egg and chips. If it was well done and maybe had a slice of tomato.”
