Life needs positive energy.A person’s life is a road with lots of difficulties and various negative emotions.Everyone will have the desperate time.Positive energy can help us go through this period of time.For example,I am sad about the exam yesterday.But an optimistic classmate encourages me to think in a good way and comfort me.I can recover soon.But if she also is as pessimistic as me,I won’t have recovered so quickly.Maybe I will be sad for a long time.There are many similar things happening in our life.To live a better life,we need positive energy.
