Justin Bieber, 15, is a YouTube singing sensation.

He has the soul of a seasoned artist. And a legion of fans to make him legit. Justin Bieber, at 15, is a singing wunderkind.

Raised by a single mom in Stratford, Canada, Justin entered a local “American Idol”-esque competition just for fun. With no formal musical training, he dazzled the crowd with his voice, not to mention his mastery of the drums, guitar, piano and trumpet. The musical autodidact came in second at age 12.

Soon afterward, he started uploading his jams on YouTube. He’s racked up more than 10 million views so far. Even Justin Timberlake and Usher started noticing him. They actually got into a bidding war to sign with him! Usher won. But, Justin Bieber is the big winner with his single “One Time” just going Platinum in his native Canada.

Aaron Fotheringham, 17, competes in extreme sports with a wheelchair.

Aaron Fotheringham has earned his “whining rights,” but he’s never touched them. He was born with spina bifida, unable to use his legs and adopted into a home with 5 other kids. None of that has ever kept him or his need for speed down.

Since he was a baby, he was right on track with the rest of the kids. There was nothing he couldn’t do. He just did it in his own way - crawling on his tummy and pretending to fly like superman down the hallway on crutches. When he was eight years old, he went to a skate park in his wheelchair and saw the tricks the guys there were doing and said, “Hey, I can do that!”

At first, he fell off a drop in a quarter pipe. But, he tried again until he started doing difficult tricks and entering free style competitions. “Wheelz,” as his friends call him, won the 2005 Vegas AmJam BMX finals, and soon after landed the first wheelchair back flip. He is the only known competitive “hard core sitter,” as he likes to say, so he competes against extreme bikers and skaters. His advice to anyone thinking about cashing in their “whining rights” - “Don't limit yourself. Just go out there – just live your life. Do something gnarly.”

Sadiya Buta, 15, is getting attention for much more than what she wears on the tennis court.

It’s 100 degrees in Arizona, but that doesn’t keep Sadiya Buta off the court. She is part of one of the top doubles teams in her high school’s division. Like her teammates, she is clad in her school’s team shirt and skirt, but Sadiya also wears an extra layer of pants, a long sleeve shirt and a hijab, as part of her traditional Muslim beliefs.

The 15-year-old is looked at like a phenom in the sport, only picking up a racket for the first time last year. Her family recently came to Tucson, Arizona from a refugee camp in Kenya. Before leaving the camp in Dadaab, Kenya, Sadiya’s family was forced out of war-torn Somalia. The International Rescue Committee resettled Sadiya, her 5 siblings and her parents in the United States.

The adjustment for “Sandy,” as her friends call her, was a challenge, to put it mildly. She acts as a translator for her family, as they all learn English and her parents look for work. Despite the obstacles, Sadiya does whatever it takes to tackle her home life with school work and tennis, including waking up at 3 a.m. to complete her homework to keep up her better-than-perfect GPA. She admits that people at school made fun of her at first, but she paid no attention, determined to keep her eye on the ball.

Kyle Taylor swam the English Channel to raise money for a disabled runner.

Like a lot of little boys, Kyle Taylor loved to swim. He was an avid swimmer until he blew out his shoulders during his first year of college. Once he started grad school in London, Kyle wanted to take up swimming again, slowly. But the “take it easy” approach lasted only until he met a boy named Harvey Perry.

Harvey was also trying to use athletics to overcome adversity, having had lost both of his legs to meningitis, he wanted to get running prosthetic legs. Even though Kyle was in pain, he pushed himself to swim the English Channel to raise money for Harvey. He trained day and night, finally swimming the the length of the coast (due to weather concerns) and raising $10,000 for Harvey to get his legs.

Kyle’s advice to other young people: “Identify what you love to do and what problems there are in your community. Try to link what you love with solving one of those problems. Stop waiting for someone else to do it. No one is coming.”

Chelsey Shannon, 17, writes for the 'Louder Than Words' book series for teens.

Chelsey was 6 years old when her mom died of leukemia. She was 13 when her father was murdered. Desperate, but hard-pressed to find the resources or a way to cope with the death of two parents, she decided to tell her story.

She is an author for the “Louder than Words” memoir series, written by teens and meant for teens. "Writing gives me a really important outlet for my emotions. Especially right after my dad's death. All I did was write. It helped me put out my feelings of extreme sadness and hopelessness and put it into something constructive," Chelsey, now 17, says.

They say the pen is mightier than the sword, but maybe the pen also helps you deal with the sword’s might. Chelsey hopes it does for her, and that she can help other young people in the process.

Becky Gulsvig, 26, stars in the national tour of the musical 'Legally Blonde.'

Pretty, blonde, donned in pink. Becky Gulsvig looks like the title character she plays in the musical version of "Legally Blonde," but she says she’s only half like Elle Woods. Becky says she’s determined like her. “We have the same spirit.”

That determination took her from understudying the role in the Broadway show to snagging the role in the national tour. The determination has worked hand-in-hand with years of hard work. She made her Broadway debut as Amber Von Tussle in "Hairspray." She also made stage appearances in "Peter Pan," "Grease" and "A Funny Thing Happened on the Way to the Forum."

The 26-year-old from Minnesota graduated a year early from high school and moved to New York to follow her dreams, like the character she now plays. These days she is living out that dream, traveling from city to city, as a rising musical theater star.

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."

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.”

Elena Hight, 19, is an Olympic snowboarder.

I didn’t know what a “backside 900” was before I started reading about how Elena Hight became the first female to land one in the 2007 Winter X-Games. Apparently, it’s trick where a snowboarder rotates 2½ times in the air with their back facing down the mountain. It’s probably one of the most difficult things in the sport, but when I saw Elena do it, it looked easy, like she was dancing or something.

Elena grew up in Hawaii, far away from any semblance of snow, much less a snowboard. When her family moved to Idaho, her dad got her one of the first snowboards for kids when she was 6 years old. She was one of the only girls doing it, but she was hooked.

“Making a career out of it is fairly recent thing,” Elena says of a sport that’s been around since the '70s. Elena has done it though, with big-name sponsors and competing as the youngest member in her event in the 2006 Winter Olympics. As she looks to new, well, heights, she knows more people are watching the sport. “It’s a much bigger deal. A lot more pressure. But, I’ll be ready.”

NBA star Dwyane Wade is the national spokesman for National Recess Week.

You already know him as an NBA champion and Olympic gold medalist. You already know that Dwyane Wade still gets up after falling down seven times. But, the 27-year-old’s acts of kindness often go unnoticed.

Last Christmas, he made headlines when he bought a home for a Florida woman whose nephew accidentally burned her house down. But, the kindness isn’t random for the Miami Heat star who founded Wade’s World, an organization that helps underprivileged kids. Once again, he has teamed up with National Recess Week as the national spokesperson to encourage young people to foster a sense of community and sportsmanship.

Dwyane’s NBA bio says he wants to leave the world a better place. When I met him, he told me he told me that things he wants the world to know him for haven’t been accomplished yet. “But, they will happen,” Dwyane assures me.
