A psychoanalytic experience with Herb Strean is described as facilitating the author's personal evolution of competencies required for a successful marriage. Rather than focusing on the familiar difficulties that often beset marriage, eight core competencies (capacity for commitment, emotional maturity, tolerance for imperfections, unconscious wisdom, mature dependence, capacity for oedipal success, capacity to face existential realities, and capacity for humor and playfulness) are delineated. Many people develop these competencies from fortunate internalizations of effectively loving parental couples. Others are able to do this via supplemental mentoring experiences. The author's mentoring was received during the course of two psychoanalyses with Herb Strean.
