We are all, without exception, in the process of criticism and judgment, even if we don't necessarily realize it. If we criticize the other, it is because it reflects on us, it refers to something we do not accept about ourselves. It is much more effective to work on yourself rather than to judge the other person. It may take some awareness and effort to change this kind of behavior.
The absence of criticism greatly strengthens the bond and the relationship with the other person. The health of the couple is much better. It is much more pleasant to start a relationship in harmony and in good understanding. Self-discipline to criticize and judge less gives us a real sense of well-being. This leads me to tell you also to be careful with your environment, with your friends. The more you are in contact with people who criticize and judge, the more you will become one too.
Let's take an example. You have already been on a few dates to get to know each other better, you are at a restaurant, you give your opinion on the lack of manners of the people around you, you criticize the service of the restaurant "the food is not good enough, is not hot enough, is not fresh enough". How do you think your guest feels? Good, in your opinion? Chances are, the other person is afraid of being judged, of being criticized in turn, and will run away from the new relationship.
Stay positive, observe yourself when you realize that you are judging, criticizing, reposition yourself in a more tolerant way. You will feel much better, and so will the other person.
