One element of emotional intelligence is self-regulation, which is your ability to control disruptive impulses and moods before you act. In effect, it’s the ability to think first before acting or reacting.
Outcomes from self-regulation range from spewing whatever you’re feeling in the moment (without regard to your effect on others) to remaining poised during emotionally charged situations.
Staying calm isn’t easy to do, especially if you’re in a high-stress job where emotions flare regularly. Some of my clients suffer as they try to manage this. On the surface, they keep their emotions in check, but not too far below the surface, their emotions wreak havoc.
