What is the mentality of people who like to punch in and talk about one thing every day?

Most of them want to record their lives, just like keeping a diary, recording their own events, such as happiness, sadness, embarrassment, importance, celebration, children's childhood appearance and so on. In retrospect, it felt like looking at an old photo. They faithfully recorded the past years, faithfully kept every bit of beauty, and laughed at the way they grew up.
