One of the parts I loved was when Mortenson found out that there was a fatwa against him. A fatwa is a legal pronouncement by a religious cleric. There were some in Pakistan who were very much against a Christian building schools in their country and believed that he was trying to indoctrinate their children. On the contrary, he was trying to educate them to fight against the indoctrination going on by the Taliban in the madrassas that they were building. At any rate, Mortenson had built a strong network of allies by showing great respect for the Muslim people and their religion. As a result of the way he lived and the example he set, the higher ruling bodies overturned the fatwas against his school building.
The lesson that I took from this is that he was successful because of his integrity. He loved the people and their war-torn country, respected their differences, and lived what he believed even at great personal sacrifice. I have great respect for such a man.
