So - what to do for those days, when you wish you had writing prompts, but you can't find any?
Prepare for that day.
Collect writing prompts.
Collect writing prompts from every source you can find.
Print them out, write them on index cards, create a system that works for you. I think it would be nice to have like ATCs... big enough for pictures, small enough to comfortably have just one word written on them.
Adjust them to fit your beliefs, preferences, circumstances, etc. I mean, just because you are Pagan, doesn't mean you cannot be inspired by Christian writing prompts. We are all human.
You can write from the same prompt several times, you know. :-D
Those days when you don't need someone to suggest you what to write, write down your ideas in your writer's journal, and use them as writing prompts those days you can't find anything elsewhere.
Is today a special day? What is being celebrated today, where and why? What happened in history this day?
There's an ocean of oracle cards, divination cards, tarot cards and like.
