Firstly, the article is about much more than just the ABC speech. Read the whole thing, and don’t get hung up on that example this time.
Secondly, the ABC speech (referred to in the article) isn’t meant to be a “compass”, it’s meant to be a motivating speech. (Using threats and abuse, granted.) Note that the speech contains no actual guides, tips, or instructions on how to sell real estate. It’s essentially (paraphrasing) “Do it or you’re fired.” and “I could do it easily, so if you cant do it, you must suck.”
It may not be the best way to convey this particular message in most cases, but I could imagine situations in which it was suitable.
Your off-target criticism of the article by criticizing the ABC speech for something it isn’t reminds me of when the article much later says “So even now, some of you reading this are feeling your brain bombard you with knee-jerk reasons to reject it.”.
