Many people like to change their avatars, which is common for many reasons. For example, they want to change their avatars, for example, they are bored. For example, after seeing a very good picture, it is not as good as loving beans and having a new blockbuster. No matter which one is the reason why people change their avatars, from another point of view, it is because they have the need to change their avatars, which can be understood as the need of beauty or self-worth from Maslow's hierarchy of needs theory. It's hard to know which one it is here, because for most people, the reason and background for changing the avatar are complicated.
Then I change my avatar because of my own needs. I regard changing my avatar as an expression of my emotions. I use red when I am happy, blue when I am sad, and black when I am angry. Either way is my expression. Frequent changes indicate that individuals are willing to express their feelings and spend time in these social spaces. It also shows that they are more willing to socialize and are willing to share their inner world with others. Of course, when someone shares this with you, you will feel uncomfortable, but they are willing to do such things themselves. After all, sharing themselves is to leave their own shadow on the world.
this way of sharing is also a kind of recognition and love for yourself. Many of us think that sharing is a kind of show-off. In fact, everyone needs to express it. Reasonable expression is not a show-off. We should not label things we don't understand maliciously. In short, we should look at this issue rationally. When you want to express yourself, you can change your avatar. Even change your name and signature.
