Favorite quote. That one is hard. I have a few:
“I am only one, but still I am one. I cannot do everything, but still I can do something. And because I cannot do everything, I will not refuse to do the something that I can do.” Edward Everett Hale
“Start where you are, use what you have, do what you can.” Arthur Ashe
“Whoever saves one life, saves the world entire.”
and this one I say to myself when I send a dog over the Rainbow Bridge:
“Good night, sweet prince (princess) / And flights of angels sing thee to thy rest.” William Shakespeare”
