To be honest what happened was that I tried to write a short introduction with both stories from university, they got way too long, then wrote the writing advice, and then tried to mix them both into a coherent post, then noticed the analogy of the trunk was a good anchor and remixed the article even more around that, and this is what we got. Still I enjoyed writing it.

There's always hope for a Part II. Maybe on rhetoric; which is what I interpreted "The second most important thing" to be about. But the concepts introduced there are entirely new to me so I may be off.
