I worked on edits for the first time in a while today, and I felt so refreshed from taking a break and working on what my heart was telling me to do - even if it didn't make sense at the time or lead to anything I'm likely to publish as a book.
So, I just want to encourage the idea of following your inspiration again. As it turns out, being open to these things just invites them to occur more often. You might not be able to write an entire book without "just showing up" sometimes. But inspiration isn't as rare as it sounds if you are connected to your heart and soul... and always seeking the beauty of story and art around you.
