Optimism is important in all aspects of our life. If you can change your mind from pessimism, you can change your life.
Up to the beginning of Senior Grade Two, I did poorly in my English but I didn’t give in because I was always encouraged by both the people around me and myself. I kept practicing speaking, listening, reading and writing. When I was fed up with reading or writing, I usually entertained myself by reading some interesting English stories, jokes and humors or seeing English films. When I had some trouble in reciting or memorizing, I tried to amuse myself by playing word games or singing English songs. By this means, I always made myself cheerful and optimistic, full of splendid and colorful dreams of future. I kept practicing. Gradually, I made progress in my English. .
Thanks to the optimism, I have become one of the top students in my class by now.
