Emotions are all around us and within us at every moment. Because of emotions, the heart beats faster, the palms are sweatier, happiness, fear and love are felt or all at the same time. Emotions in certain situations can become personality traits. The function of emotions is to help in experiencing emotions, body reaction and response to emotions. Emotions have great power in the business environment. Positive emotions in business have no price because of the benefits they bring, from more original and faster solutions to greater self-confidence and motivation. Emotional intelligence is a basic characteristic of every successful individual and is necessary for professional as well as personal development. By controlling own thoughts, individual can control own emotions and controlling own emotions means control over every situation. Understanding not only one's own, but also the emotions of others is indispensable and it is necessary to always strive to understand differences. All of the above is followed by active listening, which includes listening with a purpose, providing support, giving feedback and experiencing the emotions of others while monitoring body language. Each individual communicates in a different style and experiences the world differently. Emotions have a strong influence on judgment and decision-making, but also on evaluating situations. Situations involving interactions vary in complexity, but equally vary in potential consequences. It can be said that situation assessment is a game in which there is action (interaction), at least two players and at least two outcomes. Emotions are at every step of awareness and assessment of a situation and to a large extent they create outcomes. Although there are a large number of emotions, it is possible that the exact same emotion will never be repeated, and that is exactly the importance of them. Emotions are the key to success, but it is important not to be their servant, but their master.
