I had a therapist once who told me I needed to stop "shoulding all over myself"
Same here. Banning that word from my mind has done wonders for my mental health ever since (though it took a while to eradicate and to change my thought processes accordingly).
I now think in terms of "What will I do?" and "I will do this next and then that later" or "I won't do that now/later/ever, as it's not urgent or important or a high priority", etc.
I now feel like I have choices that I am free to make according to priorities (mine as well as those of others that I take into consideration), and I am far less stressed than I used to be. And I do my best to avoid using that word with other people too. Instead, if relevant, I try to suggest options for what they could do.
