Mother Teresa:
Do you want to know how to feed a hungry world? Start by feeding one.
The same must be true on any worthwhile project - - you may not be able to provide a quilt to EVERY child, but keep working, you will have provided more quilts at the end of your effort, than if you had never even tried.
Sort of like the star fish story. "It matters to the one I make an effort for" <wave>
