    When I was about 4 years old，I decided to go to Disney World.For most young kids，it's a normal request，but I had cerebral palsy(脑瘫).Walking into anywhere，let alone a crowded place like Disney World was，to put it lightly，a tall order.Luckily，I had people in my corner to help me.Over the next three years，I worked with physical doctors，acquired a walker，and practiced walking，standing，and balance—all skills that I would need to turn my goal into a reality.

I remember the feeling when my legs would protest doing any more work.Despite this，everyone else told me I could do it，so I kept it up.It was all because of people like my parents，brothers，teachers，and doctors that I was able to grow so much，both physically and mentally.Constantly pushing me to“walk on，”yet encouraging me whenever I needed it.

On June 9，2008，as I stood in the tunnel leading into Main Street，My dad asked me if I wanted any help.I instantly replied，“No!”and situated myself facing the end of the tunnel，feet planted firmly，heart most likely beating out of my chest.Then I went，walking ever so slowly at first，then gradually speeding up.Step，step，step，step，bump.Holding fast onto the handlebars，I gathered up all my strength，picked up my walker and straightened out，picking up my pace once again.It wasn’t too long before the cheering increased because I had made it to the end，where my mom was waiting with tears in her eyes and arms open wide ready to hug her son and tell him how proud she was.

Looking back on that experience，I realize something pretty thoughtful.Every once in a while，life will throw a few bumps in the road.Though it may set you back for a bit，don’t let it stop you.Pick yourself back up and finish.It’s worth it.Besides，there just might be someone there cheering you on along the way.
