Undergraduate / "Elaborate on extracurrilar actitivies" essay; I became aware of poverty at 7 [5]

I became aware of poverty at 7, walking by my mother's side on the city's street where a beggar sat nearby with one hand extended. Normally my mother forbids interactions with strangers, much less a beggar, but that day she put the bill in my hand and told me to give it to him. "If you're good, others will be good to you" she told me afterward. From then on Her words became the guideline for all my good actions. It was why I joined Key Club, a volunteer organization. Key Club has allowed me to find new friends, explore uncharted places in the city, and help others in small but meaningful ways. My mother was right, if you're good to others, they will be good to you. But Key Club shows me a little more. It shows me that whenever I make a person smile, or stock up canned goods to feed the hungry, I'm not just for something in return, but simply performing a sacred duty to help others, knowing that somewhere in the city street, a beggar is sitting, hands extended.

~ I feel like I either miss something or stray off course. Please help!
