Why do people buy things that they don't need? 

I don't understand why many people say they can't resist the urge to shop. If you are financially well off, shopping expenses should not be a concern and won't concern you. If you are not financially well off enough to spend worry-free, there is still salvation.  Why do people buy things that they don't need? 

While putting money in other people's hands or putting up various barriers can be effective, I don't recommend it, it just imposes external restrictions and only achieves short-term goals, and in the end you still won't learn self-control. The reason for most impulse purchases is that you don't understand why you're buying - you don't know yourself, you don't understand your needs, and you don't understand the objective facts about the desired product. It's a form of cognitive dissonance, to exaggerate. 

I'm not a psychologist or a psychiatrist to give a scientific enough solution, but I can only speak my way out of it and hope it works. Yes, I may need this commodity: to clarify what my precise needs are. Try asking yourself these questions: what is this commodity being bought for? Do I need to use them in these areas? Will I be able to use it to the desired effect? At first you might think, "I bought this dress to wear, to look good and confident, so of course it's worth buying." Or, "I bought this camera to take pictures, so of course it's worth buying. This is not a good example of how to answer the above questions, so be harder on yourself: if you buy this shirt to wear, what are the chances of wearing it with all the clothes you already have on display? (Be realistic and try to underestimate) .The dress itself may be nice, but does it go well with other outfits? If it's not a good fit, the chances of wearing it drop a little more. Does the dress fit your style? You're a mature woman, is this dress only for a young woman? Do you fit the clothes? Is it too much to fantasize about being beautiful or a hottie? The camera's image quality is good, but is it portable enough? Do you take it out enough to take pictures? What subjects and scenes are you most interested in photographing? Selfies, portraits, street sweeping, landscapes, close up still life, telephoto sneak shots or bird hunting, tracking animals or children, night scenes or low light... Do the lens, sensor material and area, shutter, aperture, controls, size and weight, interface, range, etc. meet the requirements for these applications? What, you don't know much about any of this? And is your own photography worthy of this camera? 

Don't be afraid to beat yourself up; your problem usually lies in too much self-glorification and fantasy. Perhaps what I need is not the commodity: a distinction between the pleasure of shopping to satisfy a psychological need or to escape pain, and the pleasure of using it to satisfy a practical need. Some people don't shop for the product itself; the act of shopping itself gives him or her enough pleasure. Unfortunately, after the shopping occurs, it is followed by longer-term regret and loss. The reason is that the shopper needs to use the act of shopping to satisfy certain psychological needs at the time, rather than really needing the product, which leads to more evaluation of the shopping than the use, and no matter how much one buys, the desire to shop is not relieved - because the problem to be solved is always avoided. So, start by asking yourself: are you shopping for irrational emotional reasons such as depression, anger, boredom, loneliness, vanity, turmoil, x-bugs, etc.? If you don't shop, are there other ways to alleviate these uncomfortable emotions? Think again, don't simply answer "no". Or are you just running away from something you don't want to face but have to face? Does shopping help with such an annoyance? Think again, if you're running away from something, it won't come to your mind right away. Yes, I'm really going to buy this item: turn myself into a perfectionist, picking, comparing and waiting until I'm exhausted and lose interest in shopping. Okay, now that you've conquered self-doubt, dissection and criticism, you're about to make your move. But slow down! Is my information comprehensive enough? Is this merchandise good enough for you? Will there be better options elsewhere or in the future? So go ahead and ask: what's not as good about it (come on, there's no such thing as a perfect item, and the only downside is that it's expensive)? 

Keep expanding in your imagination the impact it could have. Are there other products available? Collect as much information about them as you can, study, compare, analyze, and imagine that for the same amount of money, there may be other features of a similar product you can buy that appeal to you? Or maybe buying other different types of goods might benefit more? Eventually you may turn out to be an expert in these areas, but the bills are still lying in your wallet so far. Are its flaws going to be addressed in the near future? If you can convince yourself to be patient, the "forever next generation" will be the permanent solution to your impulse shopping woes - merchants trying to squeeze toothpaste to keep making money? Don't give them any chance! Is this the last place you'll be able to find after this village? Have faith in the modern capitalist market economy that if the demand is strong enough, you can always find a replica or a good enough substitute - as opposed to being afraid of missing out on certain desirable items that can never be bought again from some fast-selling ready-to-wear brand like "Nordic Benetton"! , please convince yourself that you should upgrade your taste. As for if it's a bother to think that wasting time on this is a bad idea, or that becoming a picky perfectionist suffering from choice syndrome is also a problem.
