The Trust Equation
Trustworthiness = (Credibility + Reliability + Intimacy) / Self-Orientation
The above equation was a central part of a discussion with Charles Green, author of a series of books that have long been a favorite of mine. I own all of them and even have one in both print and audio. 
These books seem to be timeless and never more on point than the present.
