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.

想想你在花錢上是多么的吝嗇，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。

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.

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。

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.

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。

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.

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(xù)。“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，金錢、關系、時間。知道這個會改變你的人生。
