如果你不固执，你会过早放弃实验。如果你不灵活，你会把头撞在墙上，看不到你试图解决的问题的不同解决方案。
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.
Hard work beats talent when talent fails to work hard.
The man who has begun to live more seriously within begins to live more simply without.
Leadership means making tough decisions with compassion and clarity.
