In the end, we will remember not the words of our enemies, but the silence of our friends.

The only limit to our realization of tomorrow is our doubts of today.

Materials have memory; they carry time and stories.

领导力不是掌控，而是照顾你负责的人。

The key to performance is elegance, not battalions of special cases.

没有无辜，只有不同程度的罪恶。
