I've literally heard the "Tuesday" bit (that specific day, too!) multiple times recently. I don't know whether it came from your brain, which happens to be tuned to the zeitgeist, or whether everyone's getting it from AI but, either way, it's currently over-used (at least from where I'm standing). I think your point is that marketing advice needs to be practical and actionable, not just theoretical. If I were you, I'd say that more directly (with less "cleverness"). Good luck and well done for being brave and putting your thoughts out there for roasting!
