It's one of those things I've never talked about with other people, the most I've really been exposed to journal keeping in pop culture is Doug Funny. People don't talk about their personal journals.
Ever since I was a teenager I've sometimes felt compelled to write about major events, and over the years this has become the habit of keeping a journal that I write in almost every day, and sometimes I go back and read old entries. "What was I doing this time last year?" I also sometimes keep notes or such intentionally for future reference.
So, if you keep a journal, do you go back and read it? Why?
With my mental health journal, no, never.
For my hobby journal, all the time! It's neat to see how my tastes and activities have evolved, and sometimes when things get frustrating it's good to have the reminder of why I loved doing it in the first place.
