As a writer who struggles with too many ideas, I totally resonate with your quandary. I actually don’t think it’s a quandary though. I think we just have to find a way to work with our inspiration as it resonates. Maybe you work better on five projects at once? Maybe working on one project will burn you out? Part of it is discovering your writing process... I have explored the idea of a writing coach for book projects, as that is where I also feel my momentum would peter out. Having a coach and editor or another writer that you can bounce your writing off of can be an awesome support…. At least I’ve found that to be really helpful! ❤️
