On the one hand, we should become very calm and calm psychologically. Facing the unexpected. Keep your logic in order. There should be a rational analysis of this matter, not a blind impulse. I remember there was such a steady person around me. He can always keep his logic clear. It's always right to ask him in an emergency, because he can really solve these problems. And I admire such a calm person. I also hope that you can become a very stable person.
On the other hand, we should be stable enough in character. Don't panic, don't mess, and be able to control your emotions calmly. For a good example, such a thing happened to me. I remember that the exam came suddenly that year. We are not in exam week. Then, the sudden exam caught everyone off guard. Steady people can always cope with these exams. Because they are very stable and serious in their daily life and study. Unlike those who are in a hurry, they always review or preview before the exam. This is really the most important performance of a calm person.
