I read this twice, which was a good thing, because the first time, I just had no time for it. Fan of his poetry, by his Ars Poetica or Art of Poetry simply didn’t speak to me.
Even on second reading, this is not going to be my go to resource, but I liked it much better. Mostly, I enjoyed his wit, which is the best part of his poetry. But it’s no Poetics (the Aristotle one; which I also read recently and am kind of over it; yes, he is arguably the greatest thinker who ever lived, but I am just not seeing anything more for me when I re-read The Poetics).
But, I appreciate his modulated advice to write what you emotionally know, to not let correctness lead your to smooth all the roughness which gives a poem emotional power, and also be sure that you know your audience when you read aloud.
