IQ, at best, probably contributes about 20% to the factors that help determine a person’s life success. EQ, on the other hand, can be much more powerful and contributory to success in life than IQ. (Goleman, Daniel, PhD. Emotional Intelligence. NY: Bantam Books, 1995, pp 33-36)

IQ is a measure of intelligence quotient. EQ is a measure of emotional quotient. (Singh, Dalip. Emotional Intelligence at Work. India: Sage Publications Pvt. Ltd. 2006, pp 50, 59-64)
