    Now，people's life is full of choices.I want to choose this，wait!That one seems better than this one.I should make a decision after looking through all of them.As a result，they often spend much time deciding what to buy.In the end，they usually lose the happiness of getting new things and forget what's truly important.
    The situation is quite normal for humans.And psychologists call it paradox （矛盾） of choice.These words first appeared in a book by an American psychologist Barry.
    In the book，he found that many people were getting happier when they knew there were many products for them to choose.However，as the number of choices went up，people got more worried because they spent more time telling the differences between the products.The more time people spent，the more unhappy they seemed to be.
   To solve the problem，Barry gave some advice in his book for shopping.Firstly，it's important to know what we need a product for.Before we know it，don't start using the shopping app on our phones.Secondly，if we have different needs at the same time，place them from the most important to the least important.For example，some people may think the price is the most important，and others may take the look of the products more seriously.Finally，if you have a few possible choices at hand，just choose any one.Stop thinking of how your life will be different if you choose.
