Perhaps it will be clear if we unpack the meaning of the term "compelling".
The word is made up of two parts: "com", meaning "obtain gratification", and
"pelling", meaning "while falling down the side of a mountain". These anagrams
don't do that for me. Perhaps your initial conditions were more favorable than
mine.
Cheers,
