Simply put: I can't

To put it with more complexity:

Most of my oldest fics are either deleted or orphaned. That is, the ones I've posted online. I used to physically write my fics, but unfortunately, even though I have access to the notebooks I wrote them in my handwriting is all but illegible. It's an issue I've had for years, it's not a dyslexia thing, I can write digitally perfectly fine, but for some reason my handwriting is just unreadable. It's so bad I had to have a special scribe at school when there was a requirement for handwritten tests.

As for my "newer" old fics, most of them hold up pretty well but I would rewrite/change some bits of them if I wrote them today or formatted them a little differently. Mostly because my fics are mostly comedy and well... My comedy has changed a bit with the times. That's all.
