Emotional Intelligence (a.k.a. EI or EQ) is wisdom about, and ability to deal with, emotions.
Emotional intelligence is developed, not automatic. Increasing your emotional intelligence makes life better.
Ideally, year by year we grow in emotional intelligence. As we experience various emotions we can recognize them faster and identify what has worked or not worked for us in the past when faced with that same emotion. If we feel rejected, recognize it, and work through it, we have developed wisdom that will help us the next time we feel rejected. When we go through life pretending we don’t have painful emotions, we don’t develop that wisdom. We may be 55 years old but are 14 emotionally. Still, all is not lost; we just have to play catch-up.
