I've spent the majority of my life trying to "do unto others as I would have them do unto me."
Recently, I realized something about that Golden Rule.
Expectations of a return on that particular investment aren't part of the equation.
For example, I can listen because I would like to be listened to. But the moment I expect the "listen-ee" to become the "listen-er" I've set myself up for disappointment.
To some degree, this realization was the equivalent of learning that 1 + 1 does not always equal 2.
I was never good at math.
