Some of my favorite quotes:
UNLESS someone like you cares a whole awful lot, nothing is going to get better. It's not. -- Dr. Seuss
"I am only one but still I am one. I cannot do everything, but still I can do something. I will not refuse to do the something I can do." -- Helen Keller
"He who argues for his limitations gets to keep them." -- Not sure who wrote this, but it is a fabulous quote.
"To be nobody but yourself in a world which is doing its best, night and day, to make you everybody else means to fight the hardest battle which any human being can fight and never stop fighting." -- e.e. cummings
