"You know, I used to think it was awful that life was so unfair. Then I thought, wouldn't it be much worse if life were fair, and all the terrible things that happen to us come because we actually deserve them? So, now I take great comfort in the general hostility and unfairness of the universe."
"There comes a time when you look into the mirror and realize that what you see is all that you will ever be. Then you accept it, or you kill yourself. Or you stop looking into mirrors."
“Something Vimes had learned as a young guard drifted up from memory. If you have to look along the shaft of an arrow from the wrong end, if a man has you entirely at his mercy, then hope like hell that man is an evil man. Because the evil like power, power over people, and they want to see you in fear. They want you to know you're going to die. So they'll talk. They'll gloat.
They'll watch you squirm. They'll put off the moment of murder like another man will put off a good cigar.
So hope like hell your captor is an evil man. A good man will kill you with hardly a word.”
