Sir Edmund Hillary, the first man to climb Mt. Everest, says, "I was just an enthusiastic mountaineer of modest abilities who was willing to work quite hard and had the necessary imagination and determination . . . I have enjoyed great satisfaction from my climb of Everest. But my most worthwhile things have been the building of schools and medical clinics. That has given me more satisfaction than a footprint on a mountain" (Mortenson and Relin 129, 130). This sentiment sounds a lot like Greg Mortenson and his reasons for wanting to build schools in Pakistan.
Why do you think people like Sir Edmund Hillary and Greg Mortenson find more satisfaction giving rather then taking?
