Illustration and how it enhances understanding and communication is a passive interest of mine. I found the following:
“Craft more pregnant phrases that tend to stick in the mind of the hearer”
Illustration doesn’t mean a story; it could be a single word as in this case. I thought this a particularly good example of a self-illustrating sentence.
I don’t know if I agree with the sentiment expressed, I’m not sure: Is this writer advocating shock tactics?
