参考范文

     I Believe I Can Fly is a nice song by R．Kelly．This song tells us that confidence is very important．When a person has confidence，he believes in himself．He believes that he can and will succeed，and this gives him the courage to try new things．Dreams and confidence are what keep us going on in the face of difficulties．No one can achieve success without them．If you believe you can fly，then you can really fly someday．

     I think I will never give up whenever I meet any difficulties．I’ll remember confidence is the promise for achieving success forever．
