Second, selfish people are most afraid of trouble, because in their inner world, interests are above everything else and nothing can be lost. Others serve themselves best. They don't want to be disturbed by others, don't want to help others, and are even more afraid of trouble.
Third, people who have helped others but have been hurt by others are most afraid of trouble. Because my kindness has been hurt by others, or because of money, or because of something, I left my painful feeling.
Fourth, introverts are most afraid of trouble. In daily life, introverts are closed-minded because they don't want to meet and talk with outsiders, so they are most afraid of being asked about their heads! Most afraid of trouble.
In short, there is a gap between people, and there are all kinds of people. This is the diversity of human nature. We just need to get used to it and recognize it in our daily life.
