Some things ........
some of us are not meant to do. It isn't easy to begin, then carry through to the end a long piece of fiction.
Even harder to revise, rewrite, edit as most of us have to do. I find the first part easy, the second very hard.
I can easily visualize my work, but am not able to illustrate it. The best I can do is paint as rich a picture in words as I can.
Sometimes it works, most of the time it doesn't. Which is why that part of my W/P file folder is about 5 GB. It's full of failures I keep just to remind myself how bad I can be, and to not make that mistake again.
