Wheaton mom Shayne Moore's to-do list most days resembles that of many other suburban Chicago mothers.

She goes to the grocery store. She picks up the kids from school and practice. She cooks dinner. She puts everyone to bed, then gets them up to start over the next day.

Moore knows she's just one mom among many, but after hearing a message from Bono during a U2 concert at her alma mater, Wheaton College, in 2002, she decided to join her single voice with others to affect change.

"I went that night just to see Bono, but I say that what I saw changed the trajectory of my life," Moore says. "I was unprepared to hear that 9,000 Africans die a day from diseases that are preventable.

"I left that night kind of angry and indignant. ...I left that night thinking, 'Why didn't I know this? Why aren't we talking about this every night on the news and every Sunday from the pulpit of our churches?"

So she began educating herself.

At the time, ONE, a grassroots advocacy and campaigning organization that fights extreme poverty and preventable disease, didn't exist. Moore became one of the group's original members.

Since then, she's been in commercials to promote ONE and has brushed shoulders with the likes of George Clooney and Julia Roberts. She has been to Africa three times and Honduras once. This February she'll head to Cambodia.

Her book, Global Soccer Mom, shares her experiences meeting mothers all over the world.

It was during her trip to Honduras where Moore met a woman who made her realize the purpose of her new mission.

Rose was a Honduran woman with four children-two of them HIV positive, like their mother, and two HIV negative. "I'd never seen a slum, I'd never seen people living like dogs."

Rose approached Moore, grabbed her face and started speaking to her in Spanish. "She was saying, 'You're an angel, you're an angel. You were sent here to hear our troubles and tell our story to the world.' She probably died within two weeks of my visit, but that meant something to her. I've taken that pretty seriously. When I flew home I said to myself, at least I can tell her story."

So she did.

At the end of the day, Moore knows what she's doing is right. In her book and on her website, Moore shares one of her most notable quotes.

"I'm only one woman. I live in one town, I go to one church, and I have one voice… but I've come to believe that all our ones add up."
