I think there's a mythology that if you want to change the world, you have to be sainted, like Mother Teresa or Nelson Mandela or Archbishop Desmond Tutu. Ordinary people with lives that go up and down and around in circles can still contribute to change.
Landmines distinguish themselves because once they have been sown, once the soldier walks away from the weapon, the landmine cannot tell the difference between a soldier or a civilian - a woman, a child, a grandmother going out to collect firewood to make the family meal.
Even soldiers from the Vietnam War had said that when they were fighting in that war, the landmine was just one of any number of weapons to use in the fighting. It wasn't until they began to think about the aftermath and the legacy of landmines that they recognized the long-term, indiscriminate impact of the weapon.
For me, the difference between an 'ordinary' and an 'extraordinary' person is not the title that person might have, but what they do to make the world a better place for us all.
When I was a kid I didn't know what I wanted to be when I grew up, but I did know what I didn't want to do. I didn't want to grow up, have 2.2 kids, get married, the whole white picket fence thing.
