Tell me about my composition.

In the process of my growth, there are many happy things, like a string of footprints left in my heart, printed in my mind, accompanying me to grow up. I think the happiest thing is learning to ride a bike.

It was summer vacation, and my mother took me for a walk on Renmin Road after dinner every day. The sidewalk on Renmin Road is very spacious, and many children my age ride bicycles there. My mother seemed to read my mind and bought me a red bike the next day after work. I was so happy that I pestered my mother to learn to drive after dinner.

My mother pushed me to Renmin Road. She pointed to the car and said to me, "When riding a bicycle, sit up straight, hold the pedal with your pedal and push hard, keep your eyes on the front, keep your balance and concentrate." Hearing this, I found it not difficult to get on the bus. My mother helped me hold the car in the back. The car tilted under my feet. I'm nervous and excited, and my hands are all sweaty. I accidentally fell down. Learning to drive is not as easy as I thought. I am really arrogant. Now that you have learned, you must learn. Under the command of my mother, I practiced hard for a few days, and I was able to ride independently, although I occasionally fell down.

I am both excited and happy. I finally learned to ride a bike. This happy thing let me know what to do, as long as I work hard, I will succeed.
