Life is full of ups and downs but it is never too easy to achieve success. As the old English say goes “Failure is the mother of success.” I was asked to play in a table tennis match last term. After the match, I was confident I would win. Therefore, I failed. How sadly I was! Luckily, my P.E. teacher helped me out. He told me not to lose my heart. He also helped me my skills. With his help, my confidence returned and I come up with several new idea. The next day, though I had to play against another more experience boy, I beat him. So don’t be afraid of failure. If we can deal with it well, failure can be the mother of success.
