真相很少纯粹，也绝不简单。
Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.
Success comes when you focus on solving problems, not just making profits.
如果人们不相信你在乎他们，你就无法领导他们。
