Hey I need help on an idea...PLEASE look here

Alrighty. Well Im writing a poem. Its idea is i guess "Making a difference".
So far i have: Knowing you put a smile on someones face. You look at the world through a whole new view. You're not only making a difference in the world. But also a difference in you.
I want it to be along the lines of like helping people...making a difference, and also changing you inside. PLEASE post some suggestions on what to say and stuff...Thanks a whole bunch!
