Post the following challenge on facebook:
Offer a personal gift to the first 5 people who respond to your post. Promise to give them something awesome, from your heart, just because. Deliver those 5 gifts at whatever time you want and in whatever way you want in 2013. Give them no warning that it's coming or what it is. The only catch? All they have to do in exchange is to post the same challenge.
Enjoy making yourself and others happy
