When I was in college I was a member of the Society for Creative Anachronism (https://www.sca.org/). To provide an evening's entertainment, I adapted a folk tale, Why the Sea is Salt, into iambic pentameter.

It is meant to be performed vocally, not read. The first time I had to read it from my original manuscript (and it was a manuscript, written by hand with a pencil because this was the mid-80s). After that I decided I wouldn't perform it again until I had it all memorized. It took me over 30 years to get to the point where I was confident I had it memorized well enough to perform it without notes, but last year, over thirty years after its debut, I finally did it.

Then Covid happened. Now I recite it to myself in my head to help me fall asleep. It works remarkably well.
