There are many models of emotional intelligence, each with its own set of abilities; they are often lumped together as “EQ” in the popular vernacular. We prefer “EI,” which we define as comprising four domains: self-awareness, self-management, social awareness, and relationship management. Nested within each domain are twelve EI competencies, learned and learnable capabilities that allow outstanding performance at work or as a leader (see the image below). These include areas in which Esther is clearly strong: empathy, positive outlook, and self-control. But they also include crucial abilities such as achievement, influence, conflict management, teamwork and inspirational leadership. These skills require just as much engagement with emotions as the first set, and should be just as much a part of any aspiring leader’s development priorities.
