I am studying in a university now. The most basic thing for me to position myself is to classify myself as a "college student group" according to my education and level. I usually pay special attention to the sensitivity of new media articles or all kinds of information with the words "university", "university" and "18-25", so I can't help but click in and have a look. When shopping, products with these words will consider whether they belong to this group. Do I need these standards?
There are also many parents who pay special attention to health articles when they are studying, so the circle of friends is tired of elderly parents forwarding these articles all day and paying too much attention to expert articles. In fact, they classify themselves as "middle-aged and elderly people" and "need to rely on external forces to remind themselves of their health" and forward these articles to people they care about. In their minds, they think those are reliable ways to keep healthy, and hope that their friends and children can see them and follow their example to keep healthy.
In fact, I personally think that there are many reasons why self is substituted into different categories, which are closely related to the experiences of different individuals. Our society just likes to label others and classify ourselves as a certain group.
Man is a social animal. This sentence did not lie to me.
