Emotions play a significant role in directing and shaping behavior and personality of an individual. Whatever they (emotion) may be, the form, frequency and its intensity of our emotional experience, these can be categorized into two head, positive emotions (like affection, love, amusement, curiosity, joy, etc.); and negative emotions(like, fear, anger, jealously, etc.). However, the development of both positive as well as negative emotions and the learning of their expression in a reasonable way is quite essential for our own and social well-being.

By their nature of being both positive and negative, it should not be assumed that all the positive emotions are always good, and the negative emotions are bad. While weighing their impact, other factors like frequency and intensity, nature of situations and the stimuli aroused, should also be considered. Excess of everything is bad. Emotions with too much of intensity and frequency, whatever positive or negative, bring harmful effects. But, the so-called negative emotions are essential for human welfare. For example, the emotion of fear prepares an individual to face the danger ahead. The child who has no emotion of fear is sure to get affected because it has not learnt to save itself against a possible danger.
