人为某样东西实际支付的成本至少是标价的两倍，因为买来后设置、学习、维护、修理，以及最后处置，也需要耗费精力、时间和钱。不是所有的实际成本都在价签上。实际成本是标价的2倍。
What you actually pay for something is at least twice the listed price because of the energy， time， money needed to set it up， learn， maintain， repair， and dispose of at the end. Not all prices appear on labels. Actual costs are 2x listed prices.

在需要技巧的地方，武力没有用武之地。
我们成功的真正标准不在于开采了多少吨，而在于影响了多少人的生活。
