When the glass is almost half filled with the water and still you keep it filling it with water
This glass is half full of water and when more water is added, the water will fall down. No need to add more water. So the concept of GOODNESS is you don't want to add more items. Sometimes it's Okay if you can't fulfill others all requirements and always you can't give your 100% percent. Sometimes it will be overlooked. So it is better to don't add more things in Goodness. Spread Goodness Spread Happiness.
