知识和“有效”时间,两件被很多人忽视的重要投资

知识是一件值得您投资的重要事情。投资知识最简单方法之一就是阅读高质量的书籍,观看高质量的视频,并与真正的专家交谈。每月至少花费50美元在优质的书籍上。从长远来看,您将从您的投资中受益匪浅。然而,更重要的是要注意质量。这里的质量大致意味着以新知识的量/页数所衡量的信息密度。生活中的每一分钟都是重要的,所以把时间花在高质量的书本上,您可以在最短的时间内学到最多的知识。这并不是说从一本写得不好的书里学不到什么东西,但这会使您效率低下。

如果无法辨别哪本书/视频/专家足够好?您可以尝试推荐系统。我个人发现,纽约时报非小说类推荐的畅销书很实用,我参照它的建议阅读了许多优质的书籍。知道谁是专家并不难,当您遇到他们,给他们买午餐,并尝试花时间与他们待在一起。在一个小时的聊天中,您可能会学到在学校花费一年时间才能掌握的东西,善待他们必从中获利。

另一件值得您投资的重要事情就是时间。您花钱买不到额外的时间,但您可以优化它。在您做任何事情之前,请考虑它是否“有效”。如果坐公交车花1.5个小时且什么都不做,那就乘坐出租车,这样可以把无效时间减少到0.5小时,那么您就是花了20-30美元减少了一个小时的无效时间,从某种意义上就等于买了一个小时额外的有效时间,这很值得。另一方面,如果您能在公交车上看一本好书,那么这1.5小时就是有效的时间,那您可以节省坐出租车的额外费用。同样的,如果一个软件可以将您某个频繁任务的工作时间缩短50%,那么它就值50美元,买下它!

我们经常花很多钱在那些并不重要的事情上,却忘了把钱投入到购买知识和有效时间上。如果您想要更加成功,那就需要改变思维方式!只要有可能,把您的钱花在购买知识和时间上!您会终生受益!

Knowledge and Time: Two Under-Invested Items in Life

Knowledge is one important thing that worths your investment, and one of the easiest way to invest in knowledge is by reading quality books, watching quality videos, and talking to real experts. Spend at least 50 dollars on quality books each month. You will benefit from your investment tremendously in a long run. However, it’s important to watch out for quality. Quality here roughly means the information density measured in “the amount of new knowledge/page”. Every minute in your life is important, so spend it on well written books where you can learn the most in the least amount of time. It’s not that you can’t learn anything from a poorly written book. It’s just inefficient.

Don’t know which book/video/expert is good enough? Try a recommendation system. I personally found the New York times best sellers in the non-fiction category really useful. I have read many quality books using its recommendations. It’s not hard to know who is the expert. When you meet them, buy them lunch and try to spend time with them. In an hour of chat, you may learn things that can cost you a year in school. It pays to be nice to them.

Another important thing that worths your investment is time. Money can’t buy your extra time, but it can optimise it. Before you do anything, think about its cost in “effective” time. If taking the bus means 1.5 hours of sitting there and doing nothing, then take a taxi instead to cut the ineffective time to .5 hours. The extra 30 dollars you spend buy you an hour of “effective” time. It’s worth it. On the other hand, if you can read a good book on the bus, then it’s effective time, and you can save the extra money for taking a taxi. Similarly, if a piece of software can shorten your work time of certain frequent task by 50%, it’s worth 50 dollars. Buy it!

We often spend so much money on things that don’t really matter, but forget to invest in knowledge and time. This is the mindset that needs to be changed if one wants to be more successful! Whenever possible, use your money to buy knowledge and time! It’s smart investment!
