Johnny Strange, 17, is the youngest person to climb seven summits.

This is a first. I get to feature someone who beat the world record of another young person I featured. Samantha Larson was one of our first "Young People Who Rock." She was then the youngest person to reach the Seven Summits at 18, an extraordinary feat. Now, Johnny Strange holds the the record.

At 17, he Johnny completed a journey he started with his dad five years ago. There is one climb per continent, including Mount Everest and Mount McKinley. His final summit climb was Australia's 7,310-foot Mount Kosiuszko.

Johnny didn't leave the tallest for last. He says that was because he wanted to appreciate the lone experience and not just part of the seven summit goal. At the end, he sent an email to his friends and family saying, "Never let anyone stifle your dreams no matter the feat, for if you have the heart and the courage, impossible is nothing."

Jaclyn Murphy, 14, and her dad started the Friends of Jaclyn Foundation to match ill children with sports teams.

Clad in Wildcat purple, you’d think she was another player . Jaclyn Murphy, 14, is too young to be a player. But, she’s definitely part of the women’s lacrosse team at my alma mater, Northwestern University.

After being diagnosed with a malignant brain tumor, she spoke to the team in Chicago. So moved by her story, they “adopted" her. The relationship was symbiotic. The team gave her hope through her medical treatments and Jaclyn gave the team something to play for. And play, they did. I remember watching Jaclyn rush the field when “her team” won their first national title in 2005. And, the ladies continue to win. Jaclyn has celebrated all five straight national titles with the players.

After seeing how she and the team thrived together, Jaclyn and her dad started The Friends of Jaclyn Foundation. It’s an organization that matches up other kids like Jacyln with sports teams across the country. So far, 100 kids have been matched with 300 teams on a wait list.

Josh Shipp, 28, dishes out 'advice with attitude' to teens.

Our generation doesn’t have a “Dear Abby,” but we do have a “Hey, Josh.” Josh Shipp offers up “advice with attitude” to Generation Y. He says he reaches the audience too old for “Bob the Builder” and too young for Oprah and Dr. Phil.

In his 28 years, Josh has collected a lot of adventures to draw on for advice. He grew up as a foster kid, dealing with suicidal thoughts, abuse and general teenage angst. He got in trouble in class one day for talking. "When you make your friends laugh they're listening to you. Now, what will you say to them?" Josh remembers his teacher saying to him. “It really struck a nerve with me,” he says.

Josh reached that captive peer audience with a Web site that generated 100,000 emails in the first year. He has written an advice column in CosmoGirl and slings advice on MTV’s TRL. “I want kids to know that it's not about your past but it's about your future. Past challenges don't matter. Those things are part of your story but not your whole story. Life is about attitude and choices,” Josh says of the underlying message to all of his advice.

Jordan Coleman, 13, funded the documentary 'Say It Loud' to make a positive impact on his community.

Jordan’s friends want to be the next Michael Jordan or rap star. But Jordan wants young African-American boys like him to focus on going to college first. Jordan, 13, used the money he made from being a voice-over actor on the Nickelodeon show “The Backyardigans” to get that message across through a documentary.

The 48-minute documentary is called “Say it Loud,” featuring Ludacris, Rev. Al Sharpton and Newark, New Jersey Mayor Cory Booker. Jordan says, “We wanted kids who are getting good grades, or men who’ve graduated from college to 'say it loud,'" Jordan says about the title of his film. “They need to be proud of what they’ve done and make sure they’re sending that message along with being a good athlete or a musician.”

Jordan is trying to show his peers that school is cool. His favorite interview of the movie was Kobe Bryant. “I never knew that his SAT scores were so high. He had such good scores he could’ve gone to any college he wanted to.”

Matt Certner, 18, founded the Sports Clinic for Children with Special Needs.

Mikey and Matt were best friends. They vacationed together, they played sports together. But when Mikey was diagnosed with autism, the dynamics changed. “Particularly when he would try to play sports. Either the coaches would be too competitive to let him really participate or the kids would be callus,” Matt Certner says of the impetus for him starting Sports Clinic for Children with Special Needs.

Matt wanted to let kids like Mikey have a chance at an even playing field if they wanted to play sports. Matt started with one clinic in his hometown in New Jersey with volunteers from his high school, but in 2 1/2 years, the non-profit group has expanded to six in the state, helping approximately 100 special needs kids and their families. The kids play soccer in the fall, basketball in the winter and baseball in the spring. Like any other sports clinic, the kids get uniforms and trophies.

Matt, now 18, is going to Duke in the Fall, but plans to continue his work. “People say to me all the time, ‘Matt you got into college already, why are you still doing the clinic?’ I don’t do it for resume status. Ever since I was young I wanted to give back. I love it. I love the kids.”
