"Do whatever you can, with whatever you have, wherever you are."

"I expect to pass through this world but once. Any good therefore that I can do, or any kindness that I can show to any fellow creature, let me do it now. Let me not defer or neglect it, for I shall not pass this way again."

"No one can do everything, but everyone can do something."

"Don't let what you cannot do interfere with what you can do."
