Noticing
Self-awareness begins with knowing, in real time, what you feel and why.
How well do I understand emotions?
Emotional intelligence, popularised by Daniel Goleman, is usually described across five areas: self-awareness, self-regulation, motivation, empathy and social skill. Claims such as "80% of success is EQ" are weakly supported. Research finds EQ measures related to performance in roles where interpersonal work matters, but their explanatory power beyond established measures such as intelligence and conscientiousness tends to be modest.
Self-awareness begins with knowing, in real time, what you feel and why.
Self-regulation is not removing emotion but putting a gap between impulse and action.
Empathy and social skill extend into reading another view and maintaining or repairing a relationship.
The evidence for that claim is weak. Relationships with performance are observed in interpersonal roles, but the idea that it replaces established measures is closer to overstatement.
Self-awareness and regulation are reported to shift with practice. Concrete habits are commonly recommended: naming the emotion, leaving a gap before responding.
No. Self-report scales depend heavily on the state of the day and on how well you read yourself. Use it as a map of which area is thin.
Emotional intelligence results are for self-understanding and conversation. Do not use them as a basis for hiring, appraisal, or diagnosis.
