Life can be pulled by goals just as surely as it can be pushed by drives.

The best leaders are those who know how to follow.

生活太重要了，不能太当回事。

想到自己可能成为从世界上消除最大灾难之一的工具，同时怀有享受独立、家庭和平与幸福的希望，这种喜悦常常如此强烈，以至于在草地上研究我喜爱的课题时，我有时会陷入一种遐想。

History is not just about kings and battles—it's about the people who lived through it.

I couldn't remember the reason for living, and when I did it wasn't convincing.

Evolution is not just a theory; it's a fact written in our genes.

再多一点坚持，再多一点努力，看似无望的失败可能会变成辉煌的成功。
