I must have looked deep in thought，or as deep in thought as an 11 year old man can，when my grandmother glanced up from her weeding to ask，“You have something on your mind，don't you？”
“Yes，I was thinking that someday I want to be an Olympic speed skating champion like my hero，Eric Heiden，I want to be a doctor like my parents and I want to help children in Africa.”
I immediately knew I had confided in the right person when a knowing smile broke across her face.“Johann，of course! You can do anything you want to do！” she said simply.And with my grandmother's support，I set out to pursue my passions.
14 years later，I was well ready to take hold of my first dream：becoming an Olympic champion.The Olympics in 1994 were in my home country，Norway.As I entered the Olympic stadium，I wasn't the best athlete，and many had doubts about my ability to perform well.But I had something special working for me.I had a woman in the first row who believed in me following my passions just as much as I did.For the first time ever，my grandmother was going to see me skate.
It happened.Breaking a world record，I won the gold.As I stood on the podium（领奖台） that I had dreamed about my entire life，a curious question popped into my head.Why me Why did I win，given all the other incredible competitors out there The reason had to be more than a grandmother who shared a belief in her grandson's dream.The question led me to only one answer：because I wanted to make a difference in the world，and with all the media attention on my success，I could.
I immediately knew what that difference had to be：hope in the lives of the children in Africa.Six months earlier，I'd been invited to Eritrea as an ambassador for Olympic Aid.
