i kept a journal through the ages of about 18 to about 23, rather sporadically. it was okay as a way for me to remember things i was doing and people around me until a friend suggested [strongly] that i transcribe some of it here. and i did!
Just a dream diary...sort of. I always miss writing entries because when I wake up my ass can't be bothered to write that stuff down. I usually just whip out my phone and shorthand it and then use that as a cue to remember the dream. For example my last bleary shorthand note to myself was:
"Hat wolf in thug chains. No window. Tell dad, speaks wolf. Emergency! I try speak wolf. Just kid. Wants fight scene. Play final fight Matrix but Avengers."
"Jackie's mom. Tetris/Mario Kart." <-- I don't remember what this means.
"Park car on Byron's porch"
But that diary does exist in two forms, both of which are here on dA. One is just straight up me tellin' what happened and the other is me smoothing the dreams out into a narrative of sorts.
I used to! Between when I was 10 and 21! I stopped gradually, so was doing weekly entries in the end, but by then I felt like I didn't need to document my life to myself anymore. I'm not sure how to word it properly, but it's partly that I got through a fairly dramatic part of my life and didn't need to vent anymore. Maybe that's a good thing.
I still have all the old journals. Sometimes when I'm at my parents house I flip through them. It's cool to remind myself of things I've totally forgotten, either painful memories or good ones.
Is there a "sort of" option? Diary makes me think of handwriting long journal entries, but what I've got is a changed-monthly text file with a few words per day and a smiley face if I hit a goal - sort of a halfway thing between a diary and just a mood tracker. It started as a way of keeping track of how meds were affecting me, and then I got in the habit.
