Classical Sass , and I have some of the same difficulties.

When I was younger, I only wrote fiction. Then something happened (?? Life? I have no idea) and I stopped being a ‘plot’ person; I wanted to write details and descriptions and little tiny moments. All of my stories got stuck on weird things that were fascinating to me and no one else. YAY. So now I only write fiction if I have the plot set in my head. Minor changes ok, but zero plot ahead of time is a risky venture. Sigh. The book I’m working on is fantasy fiction, though! Ha. Wish me luck.
