Now listen to part of a lecture in a psychology class.
请听心理学课堂上的部分内容。

So a good example of this is something that happened to me.
关于这个的一个好例子就是我的亲身经历。
When I was younger, I had an office job and I worked there every day during the week.
我年轻的时候曾经在办公室工作过，一周工作日内的每一天我都在那工作。
And I made a regular salary from that.
我以此获得了一份稳定的收入。
But also I worked as a waiter at a restaurant each weekend, so I made some money from doing that.
不过每个周末我还会在餐馆当服务员，所以通过这份工作我也能挣一些钱。
Now, around this time, I decided I wanted to buy a house.
大约在这段时间，我决定要买一个房子。
So every time I got my regular paycheck from my job at the office,
所以每次我从办公室的那份工作领到薪水时，
I'd save as much of the money from it as I could after I bought the basic stuff I needed.
除了买一些必需品之外，我都会尽量把剩下的钱全存起来。
But with the money I made as a waiter that was another story.
不过我当服务员挣得的那笔钱又是另外一回事了。
Somehow I guess that money seemed separate from the money I earned at my regular job.
不知怎么，我就是认为那份收入和我正常工作获得的收入似乎是分开的。
So I used the money I made at the restaurant to go out to dinner, to buy videos or CDs, things I didn't really need.
于是我在餐馆挣的那笔钱便被我用来消费一些我实际上并不需要的东西，比如外出吃顿晚餐，买一些录影带或光盘。
But the thing is, it ended up taking me a really long time to save up all the money I needed to buy the house.
但问题是，结果我花了很长一段时间才存够买房子所需的钱。
And looking back now, I realize I could have bought the house a lot sooner if only I had saved more of the money I made working at the restaurant.
现在回想起来，我意识到如果当初我把在餐馆挣得的那笔钱多存下来一些，那我当时就能尽早买房了。
