如果你不能保持灵活的思路，就会抓狂，忽视解决问题的其他可能性。
If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.
I trust the process and believe in myself.
The most dangerous thing is not failure, but complacency.
我不是为纪录而战，我打球是因为热爱这项运动。
