Personality of a person who likes to use a business card with name only telephone

A simple business card, only name and telephone number, and all other information without comment.

There are no more than two kinds of people who have this kind of business card: one is that the person has a certain popularity and does not need to use the business card to do self promotion; the other is unreasonable, pretending to be mysterious to attract people's attention? Or not willing to disclose their actual situation?

No matter what kind of people, his nature is not like to open themselves. He always feels insecure. I'm afraid that people who know too much about him will deal with him or even hurt him.

This kind of person is a timid but careful person. When dealing with others, he will observe other people's conversation and all kinds of actions in a quiet way, and obtain other people's information quietly, but he tries to avoid talking about his own situation. Therefore, it is difficult for him to establish deep friendship and feelings with others.

Because this kind of person is not willing to open his inner world easily, it is very difficult for him to win the trust of his superiors and colleagues, and it is also very difficult for him to get promotion. When choosing a career, he may choose the career of freelance, or he may start his own company as the boss.
