What are the personality characteristics of people who like to scribble on paper?

Personally, I think people who scribble on paper should have a lot of ideas and always like to write them down on paper. In fact, they didn't scribble, they just expressed their thoughts on paper. If students explain this kind of person, their personality should be very introverted. Because some things are hard to say, they prefer to vent their thoughts on paper. In fact, I sometimes have this idea. Often write it on paper and throw it away. This is not promiscuity. Lang still writes his true thoughts at that time to make himself feel better and think better.
