Life itself consists of a series of challenges, whether large or small. When faced with these challenges, we should knock them back with the attitude thatyou cannot change what you refuse to confront.
Thomas Edison is a good case in point to illustrate the importance of facing challenges with perseverance. He had done a lot of experiments before the first long-lasting light bulb cameinto being. Among those experiments, there were thousands times of failure. If he had chosento give up, he wouldn't have brought so many revolutionary inventions to the world. His life isthe best evidence to prove that accepting challenges and triumphing over difficulties are whatlife is all about.
As for myself, I still remember the first time I learned to ride a bicycle when I was eight. Myfather kept his hands on the back of the bicycle to help me. I often fell to the ground when helet it go. It was painful but after I tried again and again I finally made it. Life resembles theprocess of mountain climbing. People who avoid challenges and take the easy route willgradually descend into the valleys. So we need to keep on climbing despite the twists and turns, until we eventually conquer the highest mountain and see the most beautiful view.
