"People consult astrology, cards, etc. because they are worried about the future. They want to be reassured. They don't want to worry more. Even if you really think they will go bankrupt or that their romance is doomed, don't tell them that. The trick is to tell people what they want to hear, without seeming to do so." Bluffer's Guides is a series of snappy little books containing facts, jargon, and all you need to know for instant expertise.
I read this bluffer’s guide for the humour rather than the knowledge. I have no interest in anything that is justified as ‘ancient wisdom’ in the modern world; witch burnings could also be included here (so could the world’s religions, but that is another story). Like most of these books, it is a quick read and very funny.
