地球是有生命的这一想法处于科学可信度的边缘，但并未超出其范围。

Stories you read when you're the right age never quite leave you. You may forget who wrote them or what the story was called. Sometimes you'll forget precisely what happened, but if a story touches you it will stay with you, haunting the places in your mind that you rarely ever visit.

The only way to stay ahead is to continuously innovate and adapt.

To me, fearless is not the absence of fear. It's not being completely unafraid. To me, fearless is having fears. Fearless is having doubts. Lots of them. To me, fearless is living in spite of those things that scare you to death.

不要太相信什么正直无私，对任何人都要提高警惕。
