No, I used to, but I stopped when I left home (particularly when I found my mother had read my teenage diaries). Now I keep a work diary, that's all I need, I don't feel the need to write a report on each day's events.
symbols, icons, writing, was all the same, so not everyone will understand it all.
But it certainly solves lots of arguements, ie who won what footabll match and when (yes I did do normal things too!) Whenever I am proved wrong I deny it!
I always used to, especially in the 90s when my life was a bit desperate, daily reams. I stopped once I got happy. They make awful reading that I wouldn't want to share.
