Often we are encouraged to think logically and rationally and sweep emotions under the carpet. But emotions hiding under the carpet will trip us up when we least expect it. Besides, we need emotions for assessing the environment and for making good decisions.
Emotional intelligence does not deny emotions but it does regulate them. For example, fear, is not always to be avoided. Healthy fear gives a signal that we need to pay attention. It is not always alarming. It can cause us to look both ways before crossing the street, or to lock the door.
