机会并不会如影相随，所以当它到来的时候，你最好抓住。

Being brave isn’t the absence of fear. Being brave is having that fear but finding a way through it.

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.

Resilience isn’t about avoiding failure—it’s about learning how to rise every time you fall.
