Life is a long journey, during that you are to experience ups and downs. Only by hold a proper attitude will you be able to control the unexpected in life. What happens years ago is still fresh in my mind. When Dad was out of work, my family was reduced to poor. The tough situation left me in low spirit. However, Mom stayed calm, working hardly in the field as usual. Whenever I complained on our difficulty, she always comforted me, “Don't lose your heart. Everything will be OK！" Then came the news Dad found another well-paid job. The experience taught me what important it is to be optimistic when in trouble.
