1. Emotion will affect people's personality development. People who live in depression, melancholy or fear for a long time are unpopular because of their eccentric personality and poor interpersonal skills.
2. Emotion will affect people's understanding and evaluation of themselves. When people are in negative emotions, they will lower their self-evaluation and make the attribution of "I always fail" and "I am incapable".
3. Emotion will affect people's cognitive thinking level and hinder normal thinking and learning. Nervousness, fear and irritability will hinder the speed of solving problems, and optimistic and calm emotions will help to think calmly. Anxiety and tension, if properly regulated, will not only form a "learned helplessness", but also lead to a problem that can never be solved.
