p39最后面关于money的一段话：Of course we need money to live, and we must work for it. However, some people may become too concerned with mking money and forget all about the things in life that cost nothing. Those who have little or no money may appreciate the small things they own, while those with millions in the bank may not care about anything but themselves. You could say money is a paradox. If you have none……you want some. If you have some……then you want more. If you have lots ,then you may find yourself discovering that the phrase……“Money cant buy your happiness” is conpletely true.
