— Helen Keller
You might give 10 people heartfelt notes/drawings/cards you made from the bottom of your heart; 4 of the people who received them cast them aside, and the other 4 said thanks, felt grateful at that moment but forgot about it after awhile.
But the remaining 2 made it all worthwhile. They appreciated what you made. The cards made an impact in their hearts, which in turn made a milestone in yours:
The milestone that made you believe even stronger that, your goodwill has never been silly after all.
