As the fining pot for silver, and the furnace for gold;
so is a man to his praise.

I'm a firm believer in praising people! :) Often others don't even know that what they're doing is an encouragement to others and have would no incentive to continue doing it unless some alert bystander decided to give them a gift of praise.
How long does it take, anyway? 5 seconds?
5 seconds-- and we can turn around the entire perspective someone has of their day.
