I'm also looking for good quotes to include in our non-profit newsletter. Here's one that I found:

"The fruits of your labor are lives filled with joy."

Any more suggestions?

This is one of my favorites we use alot:

"Volunteers are not paid...not because they are worthless but because they are priceless!

That is a super quote and it so true. Thanks
