My own service started when I was 12, with the small charity I launched with 12 friends. Twenty years later, millions have joined our ranks - educators, business leaders and prominent Canadians.
I met children who want to be social workers, lawyers, doctors, community activists and soldiers so they can help their people rise above still difficult economic circumstances.
Sometimes it takes a child to raise a village - or to take down an injustice.
And in rural communities we've worked alongside, Haitians are doing far more than merely recovering from the earthquake. Many are creating long-term sustainable change.
We learned that kicking down doors to free children from carpet factories isn't enough to stop child labour - we had to tackle the underlying poverty in which their families lived, through education.
There may never be another Madiba. But instead of waiting for the next Nelson Mandela to emerge, those whom he universally inspired are now looking to themselves and each other to build their own dream together.
We want to end poverty and protect our environment. But we think the most efficient way of achieving that is to change the way a generation of young people is educated. That's how you'll shift the world.
Most organizations see young people as problems to be solved. We see young people as problem-solvers.
When I was 12, I read about Iqbal Masih, a child slave who escaped the carpet factory where he'd been chained to a loom since the age of four. Iqbal led an anti-child labor crusade that made global headlines, including the one that first caught my attention.
I started calling anti-child labor organizations, asking how I could help. They told me a kid couldn't make any difference, so I decided to start a movement for young people to fight child labor, and to prove them wrong.
We've set up groups in schools across North America. They apply and receive a curriculum about different issues facing the world - from environment to health to sustainability. Then, the students take actions from fundraisers to awareness raisers, and some of them even go overseas and volunteer.
Distance and difference become irrelevant as our technology connects youth from Vancouver, Toronto, Iqaluit, Attawapiskat, Delhi, Nairobi - anywhere - to learn from and about each other.
The children of Qunu stood for hours on the side of a brand new stretch of highway as they waited for the hearse carrying Nelson Mandela to come into view.
People in the business world lament economic resources wasted on unsustainable development projects and what they see as activists' naive failure to grasp the importance of building strong economies.
While governments are not off the hook, the charity world needs to innovate and find new ways to attract outside investment to boost our social productivity.
We would love to see Canadian federal and provincial governments establish a new business entity class like the CIC or L3C for social enterprises. Our governments should also offer tax incentives to entice more entrepreneurs into the social economy, and encourage foundations and impact investors to put their capital into social enterprises.
A telephone survey says that 51 percent of college students drink until they pass out at least once a month. The other 49 percent didn't answer the phone.
Broadcasting was something, I don't want to say it came easy, but it's something I'm comfortable doing.
