I've been using Papyrus Author for a few years now, to write novel format. I can write down ideas on the side like a "Post-It board", I can separate out my chapters, and I save it multiple times, to my computer, to an external hard-drive and to the cloud. I learned the hard way once, when I didn't have a back up and had to rewrite a bunch of edits. I also write my thoughts and ideas out on paper, usually type it up and then print it out, so I have all my ideas organized. Kind of like my own story bible. I haven't published in years. I tried WattPad but didn't like it. I'm not good at self promotion, and the one book I did get published didn't sell well and the publisher dropped me. Working on my novel now, and what keeps me going is that I truly love the story that I am building and telling and I enjoy the process of writing start to finish. Even if I never make any money off it and now one reads it, I'll always keep writing.
