I always think badly of others. For example, if a person praises me as "really beautiful", I will think, "Is he laughing at me because I am ugly?" ?

Inferiority, lack of security. This is a negative self-protection behavior. Imagine bad human nature in advance, so that you can prevent yourself from slipping away in advance, which gives you a false sense of security. This false sense of security is very short-lived, because the sense of security gained through other people's behavior is not really their own, nor is it inherent in self-sufficiency. This is also a compulsive behavior, and rational people will distribute it subjectively and objectively. You think badly of others, and you have denied at least 50% of the objective influence beforehand. A good result depends on both the right time and the right place, and only one-third is subjective and two-thirds is objective.

It is suggested to change this situation gradually and imperceptibly in probability. When I am used to doing this three times, I will strongly restrain myself from thinking better of others for the fourth time. And so on, then, follow the habit twice, and restrain the habit for the third time to convince yourself that others are harmless and nothing bad will happen. If something bad happens, pay attention here, instead of blaming others first. Many things will also happen in people, weather or places, which need specific analysis. Back to the habit of three times, the habit of the fourth customer service. If nothing bad happens all the time, every reduction will force you to get used to customer service and think and act in the opposite direction.
