I’m in my 40s now and as I get increasingly aware of my limited mortality, I realise the more I can’t stand bullshit these days. Time is our most precious asset, so I’m not afraid to call out something that I know for sure is crap. I think being older and wiser also affords me the confidence to be “pissed off”, as you say.
In fact, during my last work review, my reporting officer commented that I seem rather insular because I pick and choose the ways I wish to collaborate with my colleagues. My counter to her was that if someone is going to ask me to do some ridiculous thing last minute, of course I am going to say nope because I need to protect my time.
Not sure how this would help you, but yup you are not alone
