Intimate relationship with children. Friendship plays an important role in cultivating children's happy personality. Therefore, parents should encourage their children to play with their peers and let them learn happy and harmonious interpersonal communication.

(2) Provide children with opportunities and rights to make decisions. The cultivation of happy personality is closely related to the guidance and control of children's behavior. Parents should try their best to give their children opportunities to know how to use their decision-making power from an early age.

③ Restrict children's material possessiveness. Because giving children too many things will make them have the illusion that "acquisition is the source of happiness", we should educate them with examples that happiness in life cannot be equated with possession of material wealth.

4 teach children to adjust their mental state. First of all, let children understand that some people are happy all their lives, and the secret lies in their adaptable psychological state, which can make them cheer up from disappointment quickly. When a child is frustrated, let him know that the future is always bright, and teach him to pay attention to adjusting his psychological state and restore his happy mood.

⑤ Cultivate children's extensive interests. Usually pay attention to children's hobbies, provide children with various interest choices and give necessary guidance. Children have a wide range of interests and hobbies, and naturally have a happy personality.

⑥ Keep family life happy and harmonious. Family harmony is also a major factor in cultivating children's happy personality. Relevant data show that children who grow up in happy families can live happier lives as adults than children who grow up in unhappy families.
