I love doing good deeds for people. It used to be that doing a good deed just rewarded the person with a good feeling, but you can get rewarded with a Deedcard. Visit https://www.indiegogo.com/projects/deedcard to read the details, but you can also contribute to the campaign as an investor and get a package of deedcards yourself.
You can also like the Facebook page at https://www.facebook.com/DEEDCARD and learn more about it on Facebook.
Especially in New York City, people need to do more good deeds for each other and I think if we start passing these around Manhattan as well as all over the tri-state area, you may see people becoming nicer to each other!
