The golden rule does not work. What if I like to be treated like shit?
Agreed. But it is a good default place to we start.
The real skill is empathy - to understand how the other person wants to be treated.
My empathy for others became much more effective after I started practicing empathy for myself.
It was a bit eye opening, to me, to realize how much impact a practice of self-empathy made in my relationships.

I do, as well.
I said that to myself before, as well.
But I discovered my empathy for others became surprisingly more effective after I started an intentional practice of self-empathy.
Certainly. This is what worked for me, and my relationships.
