i could make a difference in the world
I know the feeling. But usually it's a matter of failing to see and appreciate the difference we DO make. You do make a difference.
you know if i could do it all over again - life - i would become a doctor and go to africa or something
Why can't you make a difference where you are? I'm sure there are places you can help
Do you have animal shelters near you? Where homeless pets go? Or perhaps someplace that helps children?
