> The best kinds of signs tell you what other people think you are thinking, or what you don't understand.
This is a brilliant life-hack and John Le Carre captured the beauty of this kind of thinking in The Russia House . This dialogue comes from Ken Russell's excellent film adaptation:
"God, this is a list of questions that could unlock all the Sov military secrets and win the arms race at a stroke"
"Or lose it. I don't like lists, Clive. Lists tell you too much about the people who make them."
"Sir, the shopping list... It's only questions, isn't it? It wouldn't tell anyone anything? "
"Everything. It would tell what we know by telling what we "don't" know. And it would tell what we would most like to know."
