You are lucky to have as much of your work available in online publishing as you have. Forty years ago, I became discouraged at the amount of rejections, and stopped writing because I felt I was no good at it.
However, looking back at my journals and other things I’ve written, I see that I literally missed my calling. I should have stayed with essays. I was much better at that than I was at anything else.
I wish the internet and online publishing was around when I was younger! Who knows how many titles I could have had by now. lol.
