Like most of us writers from the STEM field, you have what I call the "reverse priority writing habit." We tend to put the "important stuff" at the end of our writing. A good way to get more readers and to have more impact is to put it first then explain it. This is doubly important in HN where we are exposed to so much new material, that we need a quick look so we can decide what to read and what to ignore as unlikely to be of use. Just promising something of use at the beginning is rarely enough for me. I realize that your english writing teacher probably wouldn't approve, but this is practical not academic writing.
I'd simplify the advice to say: write just one rule today and once you get in the habit of referring to it, consider adding another rule (thinking BJ Fogg and his spouse's Tiny Habits).
