Undergraduate / helping others and giving back to the community - UC Prompt 1 [3]

hey guys,
so i just began my uc essays after brainstorming for a while, and below is what i have so far for prompt #1

When I was ten years old, I dreamed of becoming either a professional basketball player in the WNBA or a professional table tennis player representing the United States at the Olympics and World Championships. Throughout the years, I have wanted to become either a stockbroker or economist, or a lawyer, a doctor, etc. But today, at the age of seventeen, if you ask me what I want to be when I grow up, what field I want to major in, the honest answer is, "I don't know."Through my experiences of giving back to society, all I know right now is that I want to lead a happy life while helping others in one way or another.

I love to smile. And I love to make others smile, which is why giving back to the community and helping others is so important to me. Not only has community service helped me learn many of life's lessons and a lot about myself as a person, but it has also given me the opportunity to help and have a positive impact on others or the environment in some way.

I was just wondering if the track im taking with this prompt is ok, and I was thinking of just talking about how I coached a 3rd and 4th grade girls snuffy basketball team and the time i coached younger kids at table tennis, but should i also mention other things like soup kitchens, beach cleanups, etc.?

Revisions, advice, constructive criticism, anything is welcome!
Thanks in advance!
