> Because of that much of the advice the therapist give benefits the client at the expense of everyone else.
Hold up there- for such a sweeping generalization, I'd argue that you need to give clear-cut examples of this effect that you call "toxic" in your next sentence. You're not grasping the target audience here or even what the "me first" attitude is if you say it's at the expense of others. Let me give several examples of the people you claim are toxic.
My fiancée is a people pleaser- she is someone this article was written for and who seeks therapy. Tell me, how is it at the "expense of everyone else" for her to now be able to politely and confidently tell her bulldozer of a friend that she'd rather go home and sleep at 23:00 in anticipation of her 06:00 shift instead of watching "classic" movies her friend wants to watch until 04:00 three or four times each week? I'd contest that it isn't.
How is it "at the expense of everyone else" for my little brother to be able to politely yet assertively tell his housemates he'd rather get a head start on his CS term project this weekend than get sloshed and deal with a hangover? I'd contest that it isn't.
How does it "create a toxic environment" for me to take some PTO to avoid burnout instead of participating in the actually toxic culture of a company that has an unlimited PTO policy but considers it taboo for anyone to take time off? I'd contest that it isn't.
I'd contest that it isn't "at the expense of everyone else" for any individual who's been raised to do anything and everything their mates, family, ecclesiastical associates, coworkers, casual acqauaintences, etc ad nauseam ad infinitum asks of them to instead say "hey, I'm going to take care of my mental health by learning to be assertive instead of burning out or being miserable forever."
There are ENDLESS comments and articles on hn lauding people who make choices to avoid burning out on their careers, about learning not to say "yes" to every request from a coworker that comes across their desk, yet I don't see anyone crying about how this is "toxic" and that it's "at the expense of everyone else"; you somehow seem to think this same principle doesn't apply to individuals in their own lives.
I hope these examples illuminate who this article is meant for and clarify what the "me first" attitude is in this context.
