I am currently using the Notes app on my phone to jot down any random ideas I have for my work in progress, for the sequel, or any other story idea for that matter. Ideas tend to strike at the craziest times, and I always have my phone with me. So it’s a lot easier to just write them down now and sort them later when I actually start working on it.
I am not writing a sequel now but my brain is already planning it when the first draft isn’t even complete. It would be such a waste to properly outline the sequel because who knows how my first book will end. It might result to me changing major plot points of the sequel. Also, already planning an outline for a sequel would make the plot for the current work rather rigid. At the same time, it would be such a waste to let a good idea go. Writing it down ensures I will not forget it when I might just need it.
As for organising details of my current wip, I am using Google Sheets, extensively. I love how I can organise everything according to my needs. Color coordinate things. Find any particular thing in long lists by using the Find feature. I also love how everything can be separately sorted in one document using different sheets. I only need to open one document and everything related to that project is there for me to pick, view and edit at the bottom.
I was doing all this in a notebook, which was getting rather messy. So I switched to Google Sheets. Though I might just check out all the softwares mentioned here. Thanks for sharing, y’all!
