Life is full of various experiences, of them some are unforgettable. I still remember the hiking experience with my classmates for 16 km a year later. That summer day, we set off early in the morning, think it would be great fun to walk for so long a distance. However, with the weather is getting hotter and hotter, I found their legs heavier and heavier. What's worse, my feet began bleeding because long time pressing against the shoes. At one point, I even wanted to give in. But I managed to drag the rest of the way to the destination.
Though not pleasant, this journey was impressive or rewarding. I learnt that life is the long journey like this. No matter what happened, we should never give up, and we will finally achieve what we want to.
