Have you seen the Smile Cards? These are very cool anonymous good deed cards that you can leave behind when you do something nice for someone. The idea is for that person to then do something nice in order to pass the card on to someone else.
It's the same basic idea as paying it forward, but it has the added motivation of "gotta do something nice to get rid of this card" thing. Not that we do kindness to get rid of our card, OF COURSE NOT, but you know what I mean. It's a little tickler to keep kindness in the front of our minds.
In the hubbub of our crazy lives it's easy to be distracted by being busy, by negativity, by the everydayness of the everyday. I love Smile Cards. Get yours today. They have free downloads at the web site. Try them out and go do some guerrilla kindness!
