Here's some ideas:
Do the Morning Pages, as suggested by Julia Cameron.
Look into a new genre - Point Horror springs to mind.
Concentrate on another income stream!
Continue the review of all the writing text books I've read - there are 6 huge notebooks full!
I didn't get far with the workbook - but I am wondering about morning pages. The idea is to get up and write 3 pages every day, about anything, in order to clear the mind.
But then what happens to the commitment to morning exercise? If it doesn't happen first thing, it so does not happen!
Incidentally, Julia Cameron encourages one to play around - artist's dates, she calls them. So I wasn't wasting time with Wordle after all.
