Even if it's a little thing, do something for those who need help, something for which you get no pay but the privilege of doing it. -- Albert Schweitzer

"We should give as we would receive, cheerfully, quickly, and without hesitation; for there is no grace in a benefit that sticks to the fingers." 

-Seneca

"The value of a man resides in what he gives and not in what he is capable of receiving."
-Albert Einstein
