P.T. 巴纳姆：奋斗与胜利·补录 541
P.T. 巴纳姆《奋斗与胜利》· Struggles and Triumphs · 领导
My friend Wilson expressed himself extremely anxious to do any service for me which might at any time be in his power. Soon after I arrived in America, I read an account of a French giant, then exhibiting in Paris, and said to be over eight feet in height. As this was a considerably greater altitude than any specimen of the _genus homo_ within my knowledge had attained, I wrote to my friend to take a trip to Paris for me, secure an interview with this modern Anak, and by actual measurement obtain for me his exact height. I enclosed an offer for this giant’s services, arranging the price on a sliding scale, according to what his height should actually prove to be,--commencing at eight feet, and descending to seven feet two inches; and if he was not taller than the latter figure, I did not want him at all.

白话
巴纳姆的朋友威尔逊表示愿意随时帮忙。巴纳姆回美国后，读到巴黎有个法国巨人身高超过八英尺，便写信请威尔逊去巴黎见这个现代巨人，实际测量身高。他附上报价，按身高滑动计价：从八英尺起，降到七英尺二英寸；若不超过七英尺二英寸，就不要。这说明，做交易前要设定可验证的标准和阶梯价格，避免为不确定的信息付高价。你可以先明确关键指标，再按结果定价。
上下文
巴纳姆在自传中回忆他请朋友去巴黎核实法国巨人身高，并按身高设定阶梯报价。
今日一问
你下次做交易前，能否先定好可验证的标准和阶梯价格？
