If you have a firm grasp of whom you are, it's difficult for someone to say or do something that gets your goat. Emotionally intelligent people are self-confident and open-minded, which creates a pretty thick skin.
Research 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. 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.
