One possible version：
One Thing I’m Proud of
I still remember how I became a good table tennis player.
The first day I went to high school, I saw some of my classmates playing table tennis. Amazed at how skillful they were, I was determined to be just as good. Later on, I often watched them carefully to learn their techniques. Then I kept practicing until I became confident enough to challenge the good players. At the end of the term I became one of the best players in my class.
I am really proud of this experience, because it helps me realize that we all can fulfill our potential and achieve our goals through hard work. It also helps me better understand the proverb “Practice makes perfect”.
