President Obama to Young Men of Color: "You Matter. You Count."

This Sunday at 7 p.m. ET, Discovery Channel and OWN: Oprah Winfrey Network will air RISE: The Promise of My Brother’s Keeper — a documentary that explores the lives of the boys and young men of color from four programs across the U.S. that are living the principles of the My Brother’s Keeper initiative.

Watch the following excerpt, in which President Obama explains how every child matters, regardless of their circumstances:

"I want every young man who sees me to know that I'm not that different from them," the President says in the documentary. "I wasn't born into wealth. I wasn't born into fame. I made a lot of mistakes -- but I kept at it."

Discovery is hosting a hub of information related to the documentary and initiative at Discovery.com/MyBrothersKeeper, and is currently hosting a pre-premiere of the documentary on Facebook before Sunday’s on-air debut.
