I watched a video on Facebook that brought tears to my eyes. A young girl wanted to get a cake for her grandfather for his birthday, but grandma didn't have enough money. A young man bought it for them.
Then there were flashback to where he was little and it was his birthday and a man bought the cake for him and gave him a note. On the note it said.. "A simple act of caring creates an endless ripple that comes back to you."
I love this video it's absolutely beautiful and speaks the truth on so many levels of paying it forward. By doing good things for other people you are creating an endless ripple in your life and those good things will come back to you.
