"The older I get the greater power I seem to have to help the world; I am like a snowball -- the further I am rolled the more I gain."; -- Susan B. Anthony

I love this quote, it simply states what it means, the older she gets the more she can help the world. You see more the longer you're alive, and you gain more experience which would make most people feel like they have a greater purpose in life than to just live. When Susan says "the further I am rolled the more I gain." She is talking about the longer she lives the more she learns and the more experience she gets out of life.
