Allow me to introduce the platinum rule: Treat everyone how you want your best friend to be treated.
The Platinum Rule is: treat others how they want to be treated. Term "platinum rule" 1979 possibly coined by communication researcher Milton Bennett in a paper "Overcoming the Golden Rule: Sympathy and Empathy". Concept goes further back with criticism of "golden rule" by a number of philosophers. In 1996 Troy Alessandra and Michael O'Conners write the book "The Platinum Rule" for running a successful business.
I've been trying to live by the Platinum Rule for 15+ years - today i researched it's origins.
