First comes to mind

I joined this marathon that held worldwide. Time getting too fast when I grew older and taller. I was left behind despite the longer legs I had now. I ran and ran but I see people were all ahead of me. I asked for help. Nobody turns back. So I decide to continue the journey all alone. Determined to stay alive and reach the destination. I walked and find ways to stay alive along the journey. I met few people who didn't turn back for my help just now. I saw them getting tired and gave up hope to continue their journey. I stayed with them, hoping we could know each other better. We continued the journey together. Finally after the passion, we see hope. Till the destination, I was about to bid farewell, they left me without bidding farewell. They ran ahead to the end point without turning back again. I could see happiness on their faces. I walked alone back to the end point. One of them told me , "You shall wait for no ones but continue your journey without dying , by the mean of using people, things around you, just make sure you don't die."
