時間，它是人們生命中的匆匆過客，往往在我們不知不覺中，它便悄然而去，不留下一絲痕跡。人們常常在它逝去後，才漸漸發覺，留給自己的時間已經所剩無幾。因此，珍惜時間吧，莫要再年華已老時，才感嘆時光走遠。
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麼的吝嗇，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。
但是我們大部分人都肆意揮霍著時間，對於時間的浪費，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，那我今後的一生中就都會彈奏這首曲子。這是多麼不可思議的回報。還有一些低利率、高安全率的長期投資，比如：去健身房鍛鍊、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。這條定律適用於所有事物，金錢、關係、時間。知道這個會改變你的人生。
