This document summarizes the differences between emotional intelligence (EQ), intelligence quotient (IQ), and spiritual intelligence (SQ). It defines EQ as the ability to understand and manage one's own emotions and the emotions of others. IQ is defined as a measure of academic and cognitive ability, often linked to standardized test performance. SQ is only briefly mentioned as enhancing human psychic development. The key difference highlighted is that while IQ predicts some academic and career success, EQ and other factors like work ethic and creativity also contribute to success.
