Ray Johnston would say the difference is hope.
In his newest book, The Hope Quotient, Johnston reminds us that we are generally born and "pre-programmed" with our emotional and intellectual intelligence. We can work on things as we mature, and maybe increase our EQ and IQ some, but not much. However, our "HQ" can be developed to any level. Truth is, our HQ really has more determination over our success than our IQ.
