J is for journal.
I enjoy keeping a journal, but I really am terrible at keeping up with it! Right now I have a private WP installation that I’m using. I also just started using DailyDiary, again to help with the process. I was using it back in 2006 or so. Daily Diary is a site that will email yourself questions like, “did you exercise today?” and you answer them via email. I have questions set up for many things but I haven’t set up one just for daily journaling. Maybe that will help if I can get something in my email each day.
