It is not enough to judge a person just by writing a log. After all, the human heart is a very complex and huge world. But on the whole, people who like to keep a diary show a more caring attitude towards their inner world. They are often very concerned about their inner feelings, are used to summarizing and reflecting on their thoughts and actions, and are relatively sensitive and delicate about many things-generally speaking, they should be introverted, reflective, introspective and sensitive.
