“So just do it” is a glaring one for me.
Simply because it is disregarding someone else’s thought processes and how their mind works. Where simply ‘just do it’ is not as easily and readily accomplished. This kind of advice is always uttered when one person is going on about how they’re tired of something and want to do something else. So this gets mentioned.
It could be a lot of reasons as to why, even if it is down to the obvious reasons. My valid reason a lot of the time is that I just don’t have the energy or will to just magically get myself to do something.
I remember my friend being really upset that her long term relationship failed with her partner leaving for another woman. I remember trying to empathise saying something along the lines of, “You can’t ever really trust anyone no matter how long you know them.”
I still kinda believe that however it was 100% the wrong thing to say in terms of being reassuring since it implied they’d been naive which was not the case. Their ex had all the responsibility for their relationship ending.
