创新既需要创造力，也需要严格的测试。
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.
The only limits you have are the ones you set for yourself.
我不怕被超越，因为我会一直进步。
I have always believed that the way to make money is to buy when everyone else is selling and to sell when everyone else is buying.
