安德鲁·卡内基：安德鲁·卡内基自传·补录 277
安德鲁·卡内基《安德鲁·卡内基自传》· Autobiography of Andrew Carnegie · 领导
It is hardly believable that for several years we were able to dispose of the highly phosphoric cinder from the puddling furnaces at a higher price than we had to pay for the pure cinder from the heating furnaces of our competitors--a cinder which was richer in iron than the puddled cinder and much freer from phosphorus. Upon some occasion a blast furnace had attempted to smelt the flue cinder, and from its greater purity the furnace did not work well with a mixture intended for an impurer article; hence for years it was thrown over the banks of the river at Pittsburgh by our competitors as worthless. In some cases we were even able to exchange a poor article for a good one and obtain a bonus.

白话
卡内基发现，竞争对手把高磷的反射炉渣当废料扔进匹兹堡河边，而他们自己的加热炉渣含铁更纯、磷更少，却要花钱处理。他反而把高磷炉渣高价卖给需要它的高炉，甚至用劣质渣换优质渣还拿补贴。核心是：别人眼里的废物，在懂行的人手里是资源。做法是别急着扔，先问谁需要它、它还能用在哪儿；把成本项重新看成收入项。
上下文
卡内基在自传中回忆19世纪后期钢铁业竞争，当时炉渣处理是难题，他靠信息差和需求匹配获利。
今日一问
你手头有没有被当成“废料”扔掉的东西，其实可以卖给或换给需要它的人？
