Communication is ultimately an expression of an individual's inner attitude, and to call this a
quirk of language is focusing too much on the actions without giving any thought as to the attitude that produces those actions.
If one has an internally confident, go-gettin', "always be closing" attitude, all of their actions and communication will flow from that. It's a much better use of energy to focus on cultivating a quiet confidence, rather than attempting to build up a collection of manipulative "power tricks" to be deployed in an inauthentic fashion.
Another thing to recognize is that people who are confident will pick up on the motives of these power tricks, because they'll sense an incongruity in character during communication. When someone who is typically timid and passive acts in an aggressive manner, it stands out like a nerd taking a swing at the jock. Even worse, confident people will push back to see if the user of said "power trick" is for real, which requires the next "power trick" to keep up the act.
So yeah, these might work on some people, but I personally intensely dislike it when I pick up on these things. Not that I'm the paragon of confidence by any means, but I actively rebel & push back when I feel like I'm being controlled/constrained or "should-ed" into doing something. What ultimately ends up happening with these "power tricks" is you have people like Dustin Curtis writing about how "you should do X", and then a ton of idiots mimicking the behavior and annoying the rest of us.
