No act of kindness, no matter how small, is ever wasted.
Have you ever received a smile when you were feeling down? Perhaps it was nothing more than a stranger passing you in a shop somewhere, but inside it made you feel just a little better.
Kindness is just that type of infection that grows and grows the more we nurture it. It is so terribly easy to ignore the wants and needs of others or to lose ourselves with our own preoccupations. When we look beyond our own troubles and do something kind, no matter how small, we are helping someone else to also forget their troubles for just a moment and build a little more peace on the planet.
