Good people often toil thanklessly. They don't need
recognition, but they may deserve it. 	

	"The good man does not grieve that other people do not
recognize his merits. His only anxiety is lest he should
fail to recognize theirs."   -Confucius

	By letting someone know that they are appreciated for 
their hard or selfless work, you help replenish their 
enthusiasm, their motivation. A little thanks goes a long 
way.
