Lately (by lately, I mean the past year and a half!), I've been really bad about updating my journal. I tend to pick a day and do a massive update, but I don't write much; I glue in business cards from restuarants, cards people send to me, stickers, news articles, and little things I've collected since the last update. It's sort of like a scrapbook I guess.
I think I stopped writing because I was just complaining about work (ugh) all of the time, instead of documenting what was happening in my life. Maybe now I'll start up again. We'll see. Even if I don't write frequently, I still use my journal to keep track of the things I do.
