If a person always changes his personality signature frequently, regardless of the content, this performance itself shows that his mentality and mood are very unstable in the recent stage. He may be in a period of change and adjustment of some external circumstances, or he deliberately wants to show his situation to someone or some people, but the fundamental reason is that his mentality is temporarily unstable because of the influence of external circumstances.

In addition, it is also related to age. Most teenagers are in an unstable psychological transition period, so they also like to change their signatures frequently at this stage. Signatures often have their own characteristics and want to express themselves.

Except for this age group, if you only change your signature frequently at a certain stage, it is a temporary stage of psychological instability, but if you are still fond of changing your signature in your thirties and forties, it at least shows that this person's mentality is immature.
