Sasha Dichter writes a blog which I read. He is leading a movement to create Generosity Day, an upgrade of Valentines Day. I think this is a great idea. I hope you will join in and also spread the word.
Also Sasha has a TED Talk on this subject as well: http://www.ted.com/talks/sasha_dichter.html. Sasha is Chief Innovation Officer at The Acumen Fund.
Ideally, every day would be Generosity Day, but this is a good start.
