Poor Charlie's Almanack

一句话：Charlie Munger 的言论与思维模型合集，Ben 在 Berkshire 第二部里用它给"好生意"下了一个至今流传的判据。

简介

来源未点明本书编者，正文按 Tier 0 镜像如实留空。节目讲到 Munger 被 Berkshire 纺织厂噩梦逼出一个反直觉结论——理性主义者的他意识到，经营一门生意真正该追求的是"吐出的现金多于吃进的现金，且理想状态下吃进得越少越好"；紧接着引用了 Poor Charlie's Almanack 里的一段经典类比来收束这层认知：好生意与坏生意都能赚 12%，区别在于一种能把利润在年底拿走，另一种所有多余现金必须原地再投入到旧设备上，永远见不到现金。这段类比之后，节目顺势引出 Munger 对"竞争优势/护城河"概念的最初思考。

推荐理由

Ben 直接称这本书是"极好的素材来源"，并把书中原文逐字带入节目作为论证的落点：

"This is best paraphrased in the line from Poor Charlie's Almanack, which was an awesome source... 'There are two kinds of businesses: The first earns 12% and you can take the prophets out at the end of the year. The second earns 12% but all the excess cash must get reinvested—there's never any cash. It reminds me of the guy who sells construction equipment. He looks at his used machines, takes it in as customers buy the new ones and says, "There's all my profit, rusting in my yard." We hate that kind of business.'"

这个类比把 Munger 对"竞争优势/护城河"的思考具象化——差生意即使账面利润漂亮，利润也会被 capex 锁死在院子里的旧设备上，永远无法真正落袋。
