Paying it forward is a third-party beneficiary concept that involves doing something good for someone in response to a good deed done on your behalf or a gift you received. However, when you pay it forward, you don't repay the person who did something nice for you. Instead, you do something nice for someone else. For example, if someone changes your tire while you are stranded on the highway, you might pay it forward by shoveling your elderly neighbor's walkway after a snow has fallen.

The concept of paying it forward comes from a 2000 movie Pay It Forward, starring Kevin Spacey and Helen Hunt. In this movie, a young boy, played by Haley Joel Osment, is given a school assignment that requires him to find some way to change the world. He develops the pay it forward concept, setting forth a chain reaction of good deeds. Additionally, the 1951 book "Between Planets" by Robert A. Heinlein contained the concept and is actually considered the first work to popularize the idea.

One of the most important things to remember about paying it forward is that it should be done with a selfless spirit. This means you help another person without hoping for repayment or good deeds in return. In fact, there are some organizations that allow people to pay it forward anonymously, donating money or performing good deeds without hoping for recognition. As far as the receiver of the money, gift, or good deed is concerned, he or she is told only to pay it forward.

The pay it forward concept has a firm foundation in history. Ben Franklin described it in a letter he wrote to Benjamin Webb in 1784. In this letter, he wrote about his intention to help Mr. Webb by lending him some money. However, he did not want to be repaid directly. Instead, Ben Franklin hoped Mr. Webb would at some point meet an honest man in need of financial help and pass the money along to him.

Paying it forward doesn't have to mean giving a large some of money or expending a lot of effort. It could be as simple as holding the door for someone laden with bags or giving up your place in line to someone who appears in a rush. It could even mean spending a little cash on coffee for the person behind you in line at a coffee house. For those who have money they can afford to give, there are always people in need, but even the smallest, free gestures can make a difference.
