The difference one soul makes?

I sit here tonight wondering just how much of a difference one soul can make on a world that is so bad off and I realize that the answer can either depress or uplift me. It's all in how I choose to see it. The answer is of course, not much. One person, one soul, can't do a whole lot to make this world or the people in it better. This one person can do something though. This one person can make one person's life better. Will I ever save the world? Probably not. But if I don't try, who will?

"Individually we are one drop. Together we are an ocean."

I go to that quote a lot and unfortunately it doesn't seem to get me very far. I am one drop, now I need my ocean behind me. Let's see what kind of difference 100 souls can make in this very troubled world.
