Although personality is directly related to human genes and genetic factors, it can change with the changes of environment and time. People's task is to adapt their personality to nature, society and their own health. Medical research has proved that people's personality is closely related to health and disease.

The basic principle of cultivating a good character: focus on the overall situation, start with specific things, and shape a cheerful character through your own beautiful behavior. First of all, we should recognize the harm of bad personality to physical and mental health, establish a correct outlook on life, treat ourselves and others correctly, look at and deal with problems with a broad mind, be lenient with others, be generous, not haggle over every ounce, and not hesitate. Arrange your work, study and spare time scientifically and reasonably, enrich your life content, cultivate an optimistic mood and cultivate a lively and cheerful personality. Emotional optimism: "Optimists live long" is a health motto that has been proved by practice. Spiritual optimism is not only the need of human physiological function, but also the need of people's daily life. Confucius said in The Analects: "The knower is not as good as the doer, and the doer is not as good as the musician." . It can be seen that an optimistic mood is the best spiritual nutrition to recuperate the spirit, relax the mood and prevent aging. Spiritual optimism can make the camp and health circulate, the qi and blood flow smoothly, and the vitality is vigorous, so as to be healthy physically and mentally. As Su Wen's Theory of Great Pain said: "Happiness is ambition, and camp is beneficial."

To maintain an optimistic mood forever, we must first cultivate an optimistic spirit, establish a firm belief, and achieve "Mount Tai will not bend over" and "selfless and broad heart". Selflessness is fearless, and fearlessness is calm, broad-minded and cheerful. Secondly, in the enjoyment of life, we should cultivate the idea of "contentment". For fame and wealth and enjoyment, we must always understand the truth of "less than the next, greater than the next" in order to feel the satisfaction of life and psychology. Happiness comes from feet, and happiness comes from joy, which gives birth to feelings and nurtures people. Third, cultivate a sense of humor, so that you can always smile and smile. Lenin once said: "Humor is a beautiful and healthy quality." Humor is the expression of wisdom, education and moral superiority. A person with a sense of humor must be an optimist. The direct effect of humor is to produce a smile. Optimists often laugh. Laughter is the best way to keep healthy and live a long life, and it is a good medicine to prevent and treat diseases. Modern scientific research has proved that laughter is a unique exercise method and the best gymnastics for the body. It can regulate people's psychological activities, promote physiological functions, improve living environment, cultivate carefree, cheerful and optimistic personality, and make life full of youthful vitality.

Maintain psychological balance: according to the laws of nature, the fittest survive, and the unsuitable are eliminated. Being in a high-tempo competitive environment for a long time is prone to psychological phenomena such as anxiety, mental fatigue and tension. Poor handling will affect mental health. Such as suicide, crime, psychopathy, suffering from various diseases and so on. This phenomenon is the compensation of competition and harmful to physical and mental health. In order to adapt to the development of society and ensure a healthy body, we must cultivate psychological balance in competition. There have been some negative psychological balance methods since ancient times, and Ah Q's spiritual victory method is one of them. But in essence, this method is inconsistent with the rhythm of a competitive society. Therefore, we must adopt a positive attitude and maintain a healthy mental state.

Cultivate competitive consciousness and psychological quality: the so-called competitive consciousness means having initiative and a high sense of responsibility. People's enterprising spirit is manifested in being unwilling to lag behind, full of self-confidence and daring to create. Life practice has proved that scientists, inventors, painters, innovators, etc. People who engage in creative work live longer than ordinary people and can maintain creativity for a long time. People with a high sense of responsibility are manifested in the pursuit of knowledge, skills and interests. Therefore, they have broadened their horizons and enriched their lives. To compete for the psychological quality needed by society, we must first have tenacious perseverance. Perseverance is a persistent and strong will and a powerful guarantee for mental health. At the same time, we should have good psychological endurance. Fierce competition often breaks the original psychological balance. Therefore, we must learn to self-adjust, so as to win without arrogance, lose with grace, and not worry about trifles. In any case, you can cope with new challenges with ease.

Overcome inferiority complex and eliminate jealousy: In a highly competitive society, some people may have inferiority complex after losing the game. Social needs are various, and people's interests and abilities are also diverse. Everyone has his own strengths and weaknesses, and there has never been a omnipotent "genius". Therefore, there is no need to worry about the failure of one thing and one thing and lose confidence. We should constantly sum up experience and lessons in practice, overcome inferiority complex, constantly tap our own potential, foster strengths and avoid weaknesses, and scientifically arrange work and study, which will increase the success rate. A highly competitive society is more prone to jealousy. Jealousy is a psychological phenomenon, which refers to a strong emotional state of unwillingness and resentment when others are superior to themselves in talent, morality, reputation, achievement and appearance. This negative psychological state will reduce the physiological function of the human body and lead to physical and mental diseases. Jealousy is a psychological cancer and the enemy of health. In the history of ancient and modern China and foreign countries, there are many examples of tragedies caused by jealousy. The basic way to eliminate jealousy is to cultivate the correct spirit of struggle, that is, to establish the correct concept of welcoming others to surpass themselves and having more courage to surpass others. Eliminate all bad emotions, give full play to your strengths and reach the best level in the possible range. The development of society will promote reasonable competition, cultivate competitive consciousness and adapt to the needs of society, so that we can maintain a healthy and balanced psychology in the contemporary environment and ensure vigorous energy and healthy physique, which is beneficial to ourselves and society, and is also the psychological quality that everyone should have.

Try to adjust emotions: Emotional activities are people's reflections on objective things, and they live in a world full of contradictions. Everyone has worldly desires and human emotions, but excessive emotions are extremely dangerous to human health. Therefore, we should be good at controlling and regulating external stimuli and bewitching, and eliminate them in time, so as to avoid the stimulation and harm of bad emotions. As pointed out in "A Thousand Daughters Must Be Prescribed": "Don't worry, don't be angry, don't worry, don't be afraid to laugh, don't cling to what you want, and don't be afraid of resentment. If you can not commit crimes, you will live forever. "
