Do something good and throw it on the seashore!

I heard this recently at a conference....."Do something good and throw it on the seashore" (apparently it comes from a Greek proverb)

To do something for fun and for free - purely with the intention of doing something good for someone else (without being found out), reminds me of the quote above.... and it's amazing, that when doing this, without expectation, what the tide brings in!
