I am a senior three student and I'm devoted myself to my lessons every day. I dare not waste single minute because I am afraid he will be left behind by others. With much exams to take, I feel nervous. To make matters worse, I have had difficulty in fall asleep since last week. I can't concentrate myself to the teacher in class, feeling sleepy but tired. Yesterday my parents tell me to have a walk outdoors. “All work and no play makes Jack a dull boy,” they said to me. So I followed their advices. I felt more relaxing after some rest. I have decided to take more exercise from today on.
