I'm feeling good about myself today because I'm about 10 pages shy from filling up the notebook I use for my journal. So I'll need to start looking around for new one. The one I have now is nice; it's a smaller size with a leather cover, unlined pages. I may go that route, or I might look for something a little odder. As a back-up I have a stack of those Mead Composition books in a desk drawer at home.
I know some writers think journals are evil, because they can take away time from writing fiction, articles, whatever. Mine's a big hodge-podge, though. Sure, it's a journal covering what's happening to me, but I also use it for basic writing exercises, drafts of reviews, story ideas, small fragments of stories. If I were to ever lose one, someone would find a notebook detailing the politics of my office followed immediately by some horror piece with no warning. That idea always amuses me.
Anyway. I don't know what others think, but if I didn't keep a journal I probably wouldn't write at all.
