I used to be a loser and everything which I did always had wrong. During that time, I was extreme disappointed with myself. I couldn’t do everything well however how easy it was. In the meantime, an old friend of me encouraged me to stand up again and told me that I was still young enough to try more times. I took his advices and made a great effort to achieve something. Then I found I could do things much more better. Now I not longer think I am a loser. I determined to do everything well.
