从长远来看，未来是由乐观主义者决定的。成为一个乐观主义者，不是要忽视现有的许多问题，而是想象怎么才能改善我们解决问题的能力。

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.

I'm not a person who is comfortable with confrontation, but I will stand up for myself if I have to.
