I really want to buy an Apple X, but what if I have no money to buy it? I really want to buy it. Looking at Apple X in other people's hands, I really envy it.

This is a sign of your vanity. People can take that mobile phone, which means there are conditions. People have the ability to make money by this mobile phone. Maybe his salary is not high either. He wants to save pocket money. Maybe a domestic helper. But anyway. People have the ability to buy this mobile phone.

Imagine if he used his parents' frugal money to buy luxury goods of self-satisfaction and vanity, would you follow suit?

What's your situation now? If you don't make money at school, don't think about such high things. Save money to buy it at work in the future. Don't envy others for nothing.
