Double 12 is here. How to keep the wallet?

Double 12 is coming again, another shopping spree season, so how to take care of your wallet? You need to make your own plan. First of all, I think you should sort yourself out in advance. What do you need most now? What do you already have? What is the scope of this fund that you no longer need to operate by yourself, and so on? Otherwise, if you see a lot of things, you want to go to buy buy as long as it is cheap, and you want to see them as long as it is suitable, which will cause unnecessary trouble. So, in fact, you bought a lot of things, and later found that you didn't need them at all, so if you want to buy such things, you should let others buy them as much as possible. So I think if you want to manage your wallet well, you must first plan what you must see, what you must buy, and what you can see without looking at those things, so you need to think for yourself, and then you can really see these things on that day. I won't buy if I think the price is low.
