Emotional intelligence is shown to be more useful than IQ. I think both are closely related. Your academics can and will affect your thinking process and logical reasoning which will then affect how you interact with others. If you can analyze people better and know how to interact with them, you would get through life better.
Emotional intelligence is something you can learn. Practice of talking with others and interacting socially will increase your EQ. Here, experience is the best teacher. No one is born with EQ. Changing habits and world views will change your EQ.
