Jacob Garrett McCann is just seven years old but already knows his purpose.

“I know what I’m meant for in the world. To help people,” he said.

Jacob’s parents, Kimber and Jennifer, said he discovered that calling when he was just three, during a trip to Austin.

“A homeless man had asked us for some money and he said 'we need to do something to help the homeless people,'” Jennifer said.

“It’s something he could just not get out of his mind,” Kimber added. “Like, 'I don’t understand why there are so many homeless people.'”

So when they came home, Jacob collected more than 2,000 pairs of socks to give to the homeless. Once he finished that, he started collecting toiletries, then snacks.

Here we are, four years later, and he's received hundreds of donations.

“We got a lot of good stuff,” Jacob said as he counted through his donations.

And he wants to do more.

“Because I like helping people,” he said. “And at the end of the day I’m so happy. I’m happy.”

His heart really is enormous. So much so, it’s even the name of the nonprofit he now runs.

Jake’s Heart means the world to these people. Many of them are so used to being overlooked. The fact someone volunteers his day just makes their day.

All because a 7-year-old saw a need and answered the call.

“No matter what age you are you can make a difference in the world,” Jacob said.

How wonderful could it be if, like Jacob, we all tried?
