P.T. 巴纳姆《赚钱的艺术》· The Art of Money Getting · 投资
Engage in one kind of business only, and stick to it faithfully until you succeed, or until your experience shows that you should abandon it. A constant hammering on one nail will generally drive it home at last, so that it can be clinched. When a man's undivided attention is centered on one object, his mind will constantly be suggesting improvements of value, which would escape him if his brain was occupied by a dozen different subjects at once. Many a fortune has slipped through a man's fingers because he was engaged in too many occupations at a time. There is good sense in the old caution against having too many irons in the fire at once.

白话
做生意要专注一行，认准了就坚持做下去，直到成功；如果经验证明该放弃，再放弃也不迟。就像钉钉子，一直敲同一个钉子，最后总能钉进去并固定住。当一个人把全部注意力集中在一个目标上，他的脑子会不断冒出有价值的改进想法；如果同时被十几件事占据，这些想法就溜走了。很多人本来能发财，却因为同时干太多行当而让财富从指缝里漏掉。老话说“别同时把太多铁块放在火里”，很有道理。
