Charity begins at home, but should not end there. It is when you give of yourself that you truly give. All you are unable to give possesses you. When you are kind to someone in trouble, you hope they'll remember and be kind to someone else. And it'll become like a wildfire.
Goodness is uneventful.
It does not flash, it glows. If you help others, you will be helped, perhaps tomorrow, perhaps in one hundred years, but you will be helped. It is a mathematical law and all life is mathematics. We are made kind by being kind. I cannot do everything, but still I can do something.
