Those are the only options? Okay, I'll bite. Computer. My carpal tunnel syndrome isn't happy either way, but at least with a computer, I can upsize the font so I can read the damn thing. My handwriting is limited to grocery lists, though I know I could do those on the computer, too. I don't even sign my name very often anymore, since I started using a debit card instead of checks.
This is not to say I haven't tried. A few years ago, I read "The Artist's Way," and did a few notebooks-full of "morning pages." It was quite helpful and cathartic at the time. I did a lot of purging. They definitely have to be hand-written, as you are not supposed to edit (as I'm doing now). I've kept them hidden away, every once in awhile thinking I should burn them. You're not supposed to keep them, I don't think, and they only serve to remind me of very painful times.
The drama, though; ah, the drama. Has a way of making you feel alive and important. There's that advantage of writing on a computer, particularly if, like me, the bulk of your writing has been in emails and/or yahoogroup posts -- the stuff is still there, and searchable. One reason I picked now to start a blog is I peeked into some very old posts about homeschooling, and wondered who the hell that was writing. She was so articulate and self-assured! Oh, it was me? What the fuck?
I'll answer that eloquent question in another post.
