I feel we never think about if we need or want something. Sometimes is good to get what you need, and to save your money because you never know what could happened. Even more since we are in a pandemic, and people are dying. But sometimes id good to give yourself a treat because of hard work, or whatever.

Yes, I agree with you. We buy things we don't really need and spend money very irresponsibly. We should save the money, for example, for university, for a trip, to donate it to poor people. We have to try not to spend money on the first thing we see in a shop.
