The Big Three, for me:

You Know How to Say No (to Yourself and Others)

Emotional intelligence means knowing how to exert self-control. You delay gratification, and you avoid impulsive action. Research conducted at the University of California, San Francisco, shows that the more difficulty that you have saying no, the more likely you are to experience stress, burnout, and even depression. Saying no is indeed a major self-control challenge for many people. “No” is a powerful word that you should not be afraid to wield. When it’s time to say no, emotionally intelligent people avoid phrases such as “I don’t think I can” or “I’m not certain.” Saying no to a new commitment honors your existing commitments and gives you the opportunity to successfully fulfill them.

You Let Go of Mistakes

Emotionally intelligent people distance themselves from their mistakes, but do so without forgetting them. By keeping their mistakes at a safe distance, yet still handy enough to refer to, they are able to adapt and adjust for future success. It takes refined self-awareness to walk this tightrope between dwelling and remembering. Dwelling too long on your mistakes makes you anxious and gun shy, while forgetting about them completely makes you bound to repeat them. The key to balance lies in your ability to transform failures into nuggets of improvement. This creates the tendency to get right back up every time you fall down.

You Give and Expect Nothing in Return

When someone gives you something spontaneously, without expecting anything in return, this leaves a powerful impression. For example, you might have an interesting conversation with someone about a book, and when you see them again a month later, you show up with the book in hand. Emotionally intelligent people build strong relationships because they are constantly thinking about others.
