P.T. 巴纳姆：奋斗与胜利·补录 523
P.T. 巴纳姆《奋斗与胜利》· Struggles and Triumphs · 领导
A few days elapse and it is discovered he must put in ten thousand dollars more; soon after he is told “it is all right,” but certain matters not foreseen require an advance of twenty thousand dollars more, which will bring him a rich harvest; but before the time comes around to realize, the bubble bursts, he loses all he is possessed of, and then he learns what he ought to have known at the first, that however successful a man may be in his own business, if he turns from that and engages in a business which he don’t understand he is like Sampson when shorn of his locks,--his strength has departed, and he becomes like other men.

白话
过几天发现还得再投一万美元；不久又被告知“一切正常”，但某些没预见到的事需要再追加两万，说这会带来丰厚回报；可还没等到收获，泡沫就破了，他失去所有，这才明白一开始就该知道的事：一个人不管在自己本行多成功，如果转去做不懂的生意，就像参孙被剃掉头发，力量没了，变得和普通人一样。核心是：别碰你不懂的领域。原因在于，本行的成功经验不能自动迁移到陌生行业，盲目追加投资只会越陷越深。做法是：进入新领域前先小规模试水，设好止损线，不因“再投一点就能回本”而不断加码。

你有没有在某个不熟悉的项目上，因为“再投一点就能回本”而不断加码？
