Success is no longer determined by intellectual intelligence, experience or education, but rather, by emotional intelligence (EQ). Emotions are derivations of five core feelings: happiness, sadness, anger, fear and shame and these emotions shape our behaviours. Our first reaction to an event will be emotional, and those with a high EQ are able to identify and manage those emotions and resulting reactions. Bradberry and Greaves layout the science behind EQ and describe each of the four skills (Self-Awareness, Self-Management, Social Awareness and Relationship Management) and then provide a toolkit of various strategies to improve each of the four skills.
