I keep a personal journal on my computer. Sometimes when I'm away from my computer and I really want to write in my journal, I will write in a "draft" email and then copy and paste it over to the journal document. I miss hand writing my journal sometimes, but this has proven to be much more convenient, and less space-consuming.
I've considered writing a blog, but I don't think my life would be interesting enough to other people -- sad to say! I just spend time with my family and pets, read books and magazines, and eat a lot lol.
