Emotional Intelligence or EI, according to Daniel Goleman, best author of multiple books on EI, is comprised of five key elements: self-awareness, self-regulation, motivation, empathy and social skills.
Self-awareness is the ability to recognize and understand our own motivations, moods and the effects they have on those around us. Having this self-awareness builds confidence and an understanding of how others might perceive us.
Self-regulation helps us manage our impulses and responses. Included here is taking personal responsibility, being adaptable to change, having a personal code of ethics and projecting a calm demeanor.
Motivation is not just about reciting some mantra, rather it encompasses initiative and commitment to tasks, and perseverance when facing challenges. Optimism is often seen in those who are viewed as highly motivated.
Empathy, true empathy, is really only possible when we have good self-awareness. It is when we can truly perceive others emotions and concerns, and even anticipate their needs and wants. With empathy we will be less swayed things like gossip and office politics.
Social skills are where we develop a common ground, build and manage relations and enhance our network of influence. In addition to the Communication skills listed elsewhere, it is here where we can influence others, guide and inspire them, and help defuse difficult situations using negotiation skills and persuasion.
