You just think that if you can do the same, your heart will be unbalanced for a long time, you will feel that other people's lives are better than yours, and then you will try to narrow this distance. Often people see external things and want to get close to them, so what we pursue in life is also external things.
Slowly, we will not pay attention to the internal pursuit, but only see the external pursuit, and we are also comparing external things with others. This is vanity. People blinded by vanity, life is often empty, only material can make life ripple a little, only material can fill themselves. I have a friend who is like this.
She is a girl. She studies very well in high school. Besides studying, her daily life is simply relaxing and simple. She pursues knowledge in books, and her daily life is full. After going to college, her classmates paid more attention to material life, and she was also influenced by it, and gradually began to pay attention. Let's say attention is learning.
In the end, she gradually developed a quirk. Seeing other people's good cosmetics, clothes, bags and shoes, she wants one herself. She spent all the living expenses given by her family and the money she earned in peacetime on these things. When she bought them, she compared with others and enjoyed their attention and praise. A little vanity is not a problem, but don't go too far.
