    There is always a shadow of shopping in life. You like this, look at that, and then buy a lot of things and go home. Then you calm down and find out that the shopping doesn't make any sense but waste money. How do you avoid the wrong shopping? I'll give you a few tips today!

⑴Buy good quality — and use it

    It's common for people to almost never use the things they love the most. Why? Often, it's because they want to protect the item. They like it so much and don't want it to be ruined. Instead of using their favourites, they buy much cheaper things for "everyday" use. The smarter way is to put your money on something with good quality and good style that you love very much and enjoy it the most. It stops you from wasting money on unnecessary things.

⑵Play the waiting game

    Before you decide to pay for something you like very much at first sight, wait for at least 20 minutes. Then, after clearing your head, think about how and when you'll actually use the product. Instead of simply choosing to have it or not have it, think for a moment and ask yourself whether there is something else even more important you should buy. It reminds you to save money.

⑶Buy only what you need, right now

    Besides, what makes shopping so alluring (欲罢不能的) is your idea that comes with imagining how a product can be used, such as "I will look like a princess in the evening dress at the ball one day." Before paying for a product, ask yourself if you will use it in the very near future. If the answer is no or not likely, pass.

⑷Buy for the right reason

    Research shows that we may think we're hungry when we are actually thirsty, and think we are tired when we are bored in reality. In other words, we know when we need something to satisfy ourselves, but we're not good at realizing what we truly need. It is smart to always ask yourself why you need the product before you pay for it.
