I wish I could do something about the injustice in the world but I know I am powerless to do anything because the problem are just too big for us to handle.
I can just about guarantee that the one person you might help won't think your efforts are pointless, or that you are powerless. You will have made a difference in their life.
People are not generally nasty, D. There are people out there dedicating their time and effort into making life better for others. We just don't hear their stories as often as we hear the bad ones. How many people, after Japan, do you think stepped up to help just one other person? Heroic.
