EI, or emotional intelligence, is the ability to recognize and modulate one’s own emotions, and to recognize the emotions of those around them. This is an important quality for a businessman or anyone in a company who interacts with anyone to have. It creates a pleasant work culture and boost productivity when people are happy with their co-workers. EI is also important for a company to use in regard to advertising and customer appeal. If a company truly understands and empathizes with their customers, they are more likely to succeed.
