I will never forget the day on that my father taught me how to fly a kite.
It was spring and the sun was shining brightly with wind blowing gentle. When we set off to the riverside with a new kite, I felt extremely exciting. At first my father held the kite for me, told me to run as quickly as I could when he threw the kite into the air. Although the kite fell to the ground again and again, but I kept on trying with help of my father. Finally I got the hang of them and managed to fly my kite high in the sky.
It was then that I learn a valuable life lesson: we were likely to fail many time before we finally succeeded in doing something.
