I sometimes find that once I start feeding my muse regularly again and writing more, then more ideas come. Not always. But often enough. I think it’s part of the habit of writing, at least for me. If I get in the habit of writing then something else is often right behind when I finish the last thing.
Like right now I need to finish editing a fic and post it, but I just got a lovely idea for a pwp. No wonder I like Jack Harkness so much. I ship everyone with with everyone. In every which way.
