Being emotionally intelligent certainly can be useful. It is to use these rich data set of emotions (about yourself and others) to make informed decisions.
It may very well be that you don’t think you have feelings and that you are a machine. But it’s entirely possible you have them and you are pushing them aside to “be productive”.
We get frustrated when we don’t understand why people act the way they do.
Hint: frustration is an emotion too.
But until you can accept the existence of emotions, you will not have access to this set of information, to make informed choices.
Chances are, you are working with humans, not machines. And you might be a human too.
