Even if you are in a job where the environment has grown increasingly stressful, you can retain a large measure of self-control and self-confidence by understanding and practicing emotional intelligence. Emotional intelligence is the ability to manage and use your emotions in positive and constructive ways. When it comes to satisfaction and success at work, emotional intelligence matters just as much as intellectual ability. Emotional intelligence is about communicating with others in ways that draw people to you, overcome differences, repair wounded feelings and defuse tension and pressure.
