I found this quote on the No Impact Man daily newsletter and thought I'd share it with you. It pertains to his work with environmental causes, but I think it can be applied to most areas of life:
"I also think it's important to remember that the amount by which I can do less harm is limited by the harm I do. The potential amount of good I can do, on the other hand, is limited only by my vision and imagination. It's infinite."
Have a harmless day.
