This book explains what emotional intelligence is and why it counts more than IQ or expertise for excelling on the job. It details 12 personal competencies based on self-mastery (such as accurate self-assessment, self-control, initiative, and optimism) and 13 key relationship skills (such as service orientation, developing others, conflict management, and building bonds). Goleman includes many examples and anecdotes–from Fortune 500 companies to a nonprofit preschool–that show how these competencies lead to or thwart success.
