By Bill Clinton
Think of how stingy you are with your money:if someone on the street asks for$10,you're not giving it to them.There's no way you're giving a 30%tip for a normal dining experience.And so on.
And yet so many of us just waste ungodly amounts of our time.We throw it away,every day.I know I do unless I'm careful.What helps me to not waste time is to see it as an investment,and to keep track of the returns I get for my investment.
This approach has led me to recognize that some things offer incredible immediate return on investment:a night spent learning a new song on my preferred instruments,for example,gives me a lifetime of being able to play that song.That's an incredible return.Other investments are more like low-interest,high security,long-term investments:going to the gym,eating right,etc.Some,like reading good books,are kind of a combination of both.
But many activities are worthless from an investment perspective:whatever benefit they seem to give doesn't last any longer than the activity itself.“Price is what you pay.Value is what you get.”—Warren Buffett.This applies to everything:money,relationships,time.Knowing this changes your life.

想想你在花錢上是多么地吝嗇,如果有人在街上問你要10美元,你是不會給的。普通的一頓飯要收你30%的小費,那也是沒門。諸如此類的事情還有不少。
但是我們大部分人都肆意揮霍著時間,對于時間的浪費,每天如此。除非我們刻意留心,不然我們還是明知故犯。怎樣做才能不浪費時間?不如將它看成一種投資,看看它能帶來多少回報。
在某些方面,讓我覺得(投資時間)會有不可思議的即刻回報。比如,花一個晚上的時間,在我喜歡的樂器上學會一首新的曲子,那我今后的一生中就都會彈奏這首曲子。這是多么不可思議的回報。還有一些低利率、高安全率的長期投資,比如:去健身房鍛煉、健康飲食等等。還有一些,包括閱讀有意義的書,算是兩者的結合。
但是有很多的活動從投資的角度來說是毫無價值的,除了活動本身的價值,其他的任何利益都不會得到延續。“你付出的是價格,買來的是價值。”這是沃倫·巴菲特的名言。這條定律適用于所有事物,即金錢、關系、時間。知道這個會改變你的人生。
