There's more to MC Hammer than the neon harem pants christened in his name. The hip-hop icon of the '80s is making his comeback in unexpected places: he's an ordained preacher, an angel investor, and a Silicon Valley mentor to minority-led tech start-ups.

Imagine if someone walked up to you on the street today and handed you a $20 bill. You'd probably be pretty happy, right? That will get you a good lunch. But you'd be even happier if you used the $20 to buy someone else lunch. It's true, and it's been scientifically proven.

Never tell Spencer West that he can't do something. A congenital spinal disorder rendered his legs useless, so at age five, West underwent a double amputation to remove them. His biggest challenge -- so far -- was climbing Mount Kilimanjaro for charity last June. Today, we were with West as he kicked off the We Walk 4Water campaign, starting a 300-kilometre trek from Edmonton to Calgary.

When we first met the guys from Hedley, the band wanted to embark on a Me to We Trip to Kenya. When their tattooed limbs touched down in the rural Maasai Mara, we wondered how the community would react to the Canadian rockers. Turns out the local chiefs were fascinated by the band's markings.

In 1990 when Quebec Mohawks were protesting plans by the community of Oka to build a golf course on traditional Mohawk burial grounds, a Canadian soldier thrust his bayonet into the chest of Mohawk teenager named Waneek Horn-Miller, nearly killing her. In the years that followed, Horn-Miller used sports to help overcome her trauma and anger.

Kid President Robby Novak took office in 2012, at age nine. When Robby visited the actual president last week he asked Obama what we thought was a brilliant question. Robby read to Obama from his cue-card, "How can kids and grown-ups work together to change the world?"

Amidst the chaos backstage at We Day Seattle, we found a quiet corner to talk with our good friend, the famed actor and activist. Mia Farrow is fearless. She visited our development projects in Haiti just one year after the 2010 earthquake. We couldn't imagine who she would look up to. So on We Day, we asked her.

Don't underestimate the power of a letter, especially the power of many pens. Sandi Rae, a teacher at Mt. Slesse Middle School in Chilliwack, B.C. recently wrote an email -- that counts as a letter, right? -- telling us about her Grade 9 Leadership class and their letter-writing campaign to protest funding cuts for the Rainier Hotel in Vancouver's Downtown Eastside.

Seattle Seahawks coach Pete Carroll has shown us that his football philosophy changes lives. Earlier in his career, Carroll couldn't sit back and watch as kids in L.A.'s inner-city schools succumbed to pressure to join gangs. He created A Better LA in 2003, an organization that works to reduce gang violence by offering skills training and resources for people looking to get off the streets.

For one week -- this week, Monday February 4 to Friday February 9 -- those precious discarded coins are worth the world. As part of Free The Children and RBC's We Create Change campaign to provide 100,000 people in the developing world with life-saving access to clean water, the Canadian penny has a renewed lease on life.

During his 22 years at CityTV, David Onley was an anchor, producer, science and technology specialist and weatherman. He was also Canada's first senior newscaster with a visible disability. Having lived with polio and post-polio syndrome since the age of three, he has broken down many social barriers. He has worked tirelessly to improve accessibility for all.

We know it's the thought that counts, but this holiday, why not give a gift that counts, too? Each Water Rafiki Friend Chain is unique, handmade with love by Maasai mamas in Kenya. Proceeds from the $10 chain support Free The Children's clean water programming worldwide. One chain provides one person with clean water for an entire year.

I'm told that 30 is a big step in the long march from an idealistic youth to a staunchly conservative mid-life. I'm pretty sure I won't become any less idealistic in my approaching dotage. I will still advocate for these same policies; the only difference being that as an adult my opinions are taken seriously. Why do we have such low expectations for young people?

Bullying was top of mind at We Day Vancouver, the annual event to inspire young people to make positive change, as celebrities and politicians cited B...
