The Correlation Between Emotional Intelligence and Smartness

I don't often see hand in hand stuff. I had a client that was brilliant academically and brilliant in many other ways. He didn't know how to handle some of this stuff, he did not deal with some emotional state. So the point is that I don't know if there's a correlation at all. You either reflect on your emotional state or you don't. Does it help to be smarter? I think it helps to be curious about your own emotions.
