生命的历史由突变书写。
The history of life is written in mutations.
The thing you’re most afraid to write, that’s what you should write.
You are never too old to set another goal or to dream a new dream.
Man is an animal that makes bargains: no other animal does this no dog exchanges bones with another.
人是一种做交易的动物，没有其他动物会这样做，没有狗会和另一只狗交换骨头。
