I could written this list myself, and why these platitudes are unwise and do not apply to all situations and all people.
These types of platitudes, simply show to me, a very shallow depth of thinking capacity and no wisdom.
They also covertly/unknowingly, shame people. And I see these shaming quotes/platitudes frequently.
I have come to realise, cognitive development and the capacity to know when a thought pattern is not wise, is not common. Because platitudes and cognitive distortions, are common. But the capacity to see them and discern them to be unwise, is uncommon.
I also clearly see, that society in general embracing a lack of cognitive capacity, a lack of wisdom, and instead encouraging cognitive distortions, and dysfunctional/unwise thinking patterns, is contributing to the overall mental health of society, worsening.
