Whether you pray to an old man in the sky, a saintly woman in blue, a statue, or a light pole, it won’t hurt to think about praying like this:
May I be well enough to get to my writing place;
May I be safe from the critics in my head;
May I know the joy of finding the right words;
May I be free to write what I want.
Adapt this as you will. Say it often, be happy.
