In interpersonal communication, Emotional Intelligence (EI or EQ) can be used to improve the communications between you and the other party. Emotional Intelligence can be defined as the reasoning behind emotions and using that reasoning to promote emotional growth.

There are 5 components that make up Emotional Intelligence. They are self - awareness, self - regulation, internal motivation, empathy and social skills.
Self - awareness is the awareness of one's emotions and the effect those emotions might have on the others. For example, when one is explaining his/ her idea to the other party, the amount of passion will drive the others to go along with what one has explained.
Self - regulation is about controlling oneself from acting on emotion and not thinking about first. For example, one knows that he/ she is short on cash but sees an item that one really wants, he/ she will buy it on impulse instead of thinking of how short on cash one is already in.
Internal motivation is the motivation to finish the thing that one wanted. For example, when a person is building a model kit, he/ she must have the motivation to finish the model kit instead of doing it halfway and leaving it one side.
Empathy is the ability to empathize another person's emotion.  For example, person A is complaining to person B on how hard math is. Person B can empathize with person A as person B knows how hard math is as well.
Social skills is the ability to communicate with other people on a common ground. For example, person A is able to get along with the people around and lead his/ her team to success.

When faced with an obstacle, we could use the six second's strategy to decide the choice to make. The six second's strategy require one to know oneself, choose oneself or give oneself.
To know oneself would be to have self -awareness, self - honesty and to know of one's right.
To choose oneself would be to choose the 'right' choice even though one know there are no immediate reward, prioritizing the things to do, not act rashly, be an optimist and to be able to account to oneself.
To give oneself would be to recognize another person's effort and to choose choices not based solely on one's own emotions but to the consensus of the team that one is in.

Having said these, it still is hard to understand one's emotion and there are times where even if we have this knowledge about our emotional intelligence, we would still act on impulse, not care about another person's emotion and go through with our selfishness. I hope that I will be able to control myself more and keep this in mind when I communicate with other people in the future.
