The Psychology of Money - Timeless lesson of Wealth, Greed, and Happiness - Room for Error
“You have to give yourself room for error. You have to plan on your plan not going according to plan.”
计划最重要的就是有备选方案、应急预案。对于重要的计划甚至会有几套应急预案。
“the purpose of the margin of safety is to render the forecast unnecessary. – Benjamin Graham”
对于投资来说,安全额度是让人不需要任何的预测(大部分预测还都是错误的lol)。对于不同的人安全的额度是不一样的,在不同时期也是不一样的。
“Room for error lets you endure a range of potential outcomes, and endurance lets you stick around long enough to let the odds of benefiting from a low-probability outcome fall in your favor. The biggest gains occur infrequently, either because they don’t happen often or because they take time to compound. ”
这个观点之前也提到过很多次。容错率高的方案,能让你接收多种结果,能让你更持久地待在市场中,而很多大的收获就是依靠复利和持续的投入从而遇上让小概率事件。
“To get around this, I think of my own money as barbelled. I take risks with one portion and am terrified with the other.”
这儿也模糊地提到了杠铃法则。
“If there’s one way to guard against their damage, it’s avoiding single points of failure. A good rule of thumb for a lot of things in life is that everything that can break will eventually break.”
单点失败是在很多地方都会提到的一个概念:在一个系统中,如果有其中部分的子系统只有一个而没有备份,而这个子系统的失败会导致整个系统的瘫痪。我们要承认任何事情都会最终走向“失败”,那减少或者是消除单点失败对于整体系统来说就是很重要的。其实对于公司来说也是一样,如果一个人走了,整个公司都要陷入瘫痪的状态很长一段时间,那说明这个这个人确实很重要,但作为公司的领导者,应该要减少这样的情况出现。这也就是为啥大公司大家都是螺丝钉,而领导们强调bus factor(如果你被车撞了,有人能顶上)。
