Whether your heart is healthy or not depends on whether you are positive and optimistic. Different people have different views on the same thing, which also reflects their different attitudes towards life. From the same window and the same angle, the positive and optimistic people see a beautiful picture, while the negative and pessimistic people see a devastated and desolate world. It is not difficult to find that the latter are psychologically problematic and unhealthy, and they are naturally far from happiness.

Second, some factors affecting the psychological well-being of college students

The psychological well-being of college students is also influenced by many other life situations and psychological factors, such as social support, optimism, coping strategies and study pressure. Existing research shows that with good social support, college students' psychological well-being has been significantly improved. Some people have made a comparative study on college students' attitudes towards mental health and social support during the period of SARS isolation and before SARS. The results show that with good social support, the utilization rate of social support of female college students isolated from campus is significantly higher than that of male college students and before SARS. Compared with before SARS, college students' attitudes, feelings and behaviors towards all kinds of social support are more positive, and their life pressure is obviously reduced. That is to say, the more social support college students experience subjectively, the more fully they make use of social support, the more positive and intimate their relationship with others, the more capable they are to choose and create an environment suitable for their own development, the clearer their life goals, the more meaningful their lives will be, and finally their personal growth and enrichment will be realized.

3. Suggestions on improving the mental health level of college students

The presentation and development of psychological well-being provides a new perspective and direction for the study of well-being, which just makes up for the limitations of subjective well-being in concept and measurement. Psychological well-being not only pays attention to people's emotional experience, but also pays attention to people's self-development and growth. It defines and interprets happiness from another side, which makes people feel better about happiness.
