This is the world I dream of but sometimes feel discouraged because I have but a single voice. I'm reminded of the Edward Everett Hale quote (if you don't know who this is, he's worth a search): "I am only one, but I am one. I cannot do everything, but I can do something. And because I cannot do everything, I will not refuse to do the something that I can do."
So, what can I do? I can continue trying to grow and improve myself every single day in hopes of being a good example to those around me. I can encourage positive change in my circle of influence. I can say something if I think that other people feel the way that I do and just need a little encouragement. I can vote. I can do the something that I can do.
