Part I Writing
The Importance of Keeping A Good Mood
In today‘s increasingly competitive world it is essential to maintain a positive attitude towards life. To put it in a metaphor, keeping a good mood is a foundation upon which our life is built.
Keeping a good mood is important because it can help us solve various problems in life. The following two situations can enable us to clearly see how a positive attitude helps us cope with unpleasant things. Take English learning for example. In our effort to grasp English, mistakes are unavoidable. From one perspective mistakes are annoying, but a positive attitude can make us realize that only through making mistakes can a learner be expected to make progress. Sometimes one may come down with a serious cold, feeling depressed. But a change in attitude will enable us to look at the matter from a positive perspective. The illness may teach us the importance of health.
As we can see, keeping a good mood can help us to deal with mistakes in the right way and find comfort in time of sorrow. Its importance cannot be denied.
