However, being able to regulate your emotions is a big part of EI. People who are wise and warm don't impulsively respond to things or act without thinking.

From HBR's 10 Must Reads on Emotional Intelligence :

People who can self-regulate make better decisions, are more resilient, and act with more integrity. (They also tend not to eat an entire box of donuts in one sitting while obsessively checking Instagram, but this finding has yet to be supported by the literature.)

Mindfulness is an excellent, science-backed way to self-regulate. And while a full explanation of it is wayyyy beyond the scope of this post (you can get more info here ) a little "mini-meditation" can be a big help.
