Modern people are supposed to endure a lot of pressure, from education, career or family. There are often tragic stories in the newspaper about people who went insane or committed suicide. Those tragedies once again indicate how important it is to keep a good mood.

　　Keeping a good mood under whatever circumstances is important in at least two aspects. The first one is that keeping a good mood can help people possess a right attitude towards various difficulties and challenges. For example, some people have failed in business for several times and now they are in deep debt, but they never give up their hope and still believe they have the ability to be successful. This self-confidence will surely lead them to success someday. The second one is that keeping a good mood can help people put disappointment and frustration in the right perspective. Thinking that failure is the mother of success, people can well survive the temporary blows and look forward to the right future.

　　Through the above analysis, we can realize how important it is to keep a good mood in order to face the pressure or challenges of modern society. When most people are aware of the importance of physical health, we must simultaneously remind them of the significance of mental health.
