一个人可以被毁灭，但不能被打败。
引用自海明威《老人与海》，张海迪在演讲中多次引用以表达坚韧精神
The little flower lies in the dust。 It sought the path of the butterfly。
Security is sleeping in the back seat of the car...When you're a little kid, and you've ben somewhere with your Mom and Dad, and it's night, and you're riding home in the car, you can sleep in the back seat...You don't have to worry about anything...Your Mom and Dad are in the front seat, and they do all the worrying...But it doesn't last! Suddenly, you're grown up, and it can never be that way again!
Every year of delay makes the problem harder to solve.
