I stumbled onto this blog by @Mancuniansort of by accident this morning, but this topic raises four thoughts which I'd like to share:
1) I, too, cringe at the errors - and often at the missed opportunities. As to the stories, the further back I look, the more I cringe. But no story will ever be perfect, and one finally needs to learn to live with that.
2) Usually, when I'm done writing a story, I'm so sick of proofreading and editing it looks like bathwater to me and I wonder if it's worth posting. Which is one reason why GA is so great, because the feedback makes one feel a lot better
3) A while back, I read through a story I had written a couple of years earlier in order to make sure my "facts" were right in a sequel. It's the longest story I ever wrote, and about fifteen chapters in, I realized I was so absorbed in the story I had forgotten my mission. So, rereading can sometimes be a positive experience. 👍
4) In my opinion, an editor is vital - someone to catch the typos, grammar problems, and to perform a reality check. I've worked with and without, and with is always better. In particular, @Brayonwas extremely helpful a few years back encouraging me to get a little sensory information and emotion included, and to quit writing like a computer programmer. For a couple of more recent years, @MJChas caught the errors I've missed, made sure my descriptions make sense to others, and kept me in line when I moved from improbable to impossible.
