Since Sheen started the nonprofit in 2012, millions of promises have been made and fulfilled but it all started with one.
"I once knew a man who was good with his promises," Sheen said, speaking about his father.
"He was diagnosed with stage 4 small cell lung cancer and on Sept. 4, 2012, I said goodbye for the last time. I think about that greatest quality that he had and to me, it was that he showed up," Sheen said.
Sheen's father, who was a man of his word, is being honored through his son's foundation and its role in helping others keep theirs.
"It can start from small things like a little kid saying I'll clean up my room or I'll sleep in my own room tonight," Sheen said.
The nonprofit began as a simple concept that's making a not so simple difference.
"All of our efforts matter. They stack up and think about all the promises here in Cleveland if they were just kept," Sheen said.
So far, "Because I said I would" has distributed more than 8 million promise cards in 153 countries.
