The Human Quotient (HQ) indicates how easy or difficult it is for you to make a connection (with yourself and others). The process consists of 4 levels. Our ability to connect is the key to our progress. Your HQ is more important in this than any of the other quotients: IQ, EQ, DQ, VQ, and SQ.
Consider your HQ as the total sum of all of these: The human being as a whole.
