When I was a teenager, I volunteered to give out water at a marathon. Watching the different runners who passed by and grabbed a cup was 36 . The next year I signed up for the race. I did little preparation and my only goal was to finish. On the day of the race, it was 37 hot. I remember struggling at about the 5^th mile, thinking, “I am never doing this again!”
Have you ever felt that way about something? You eagerly choose a goal 38 soon realize it is 39 to achieve than you imagined it would be. That first 10 km race was quite an experience. I jogged, I walked, I jogged and I walked. Then 40 a decisive moment. Near the end, a 70-year-old man ran past me. I felt 41 that I was younger than him but I couldn’t keep up with him. I felt defeated for a second but then I realized 42 . He was running his race and I was running mine. He had different experience, training and goals and I had mine. 43 in life do we 44 ourselves with others and feel disappointed in ourselves when we really shouldn’t? I decided, then, that one day I would be one of those 70-year-olds who were still running. 45 I crossed the finish line, I was proud of my achievement. Since then I have run several races and run purely for fun.
In life we all 46 compare ourselves with others, which is only natural. But don’t let them weaken you. 47 , you should use them to inspire you and show you what is possible. Then you are a true winner.
