——1963年6月25日在西德市政厅柏林墙前的演说

国家一定要有直言进谏的臣子，上级必须有敢于提出反对意见的下级，议论国政的人不停止，各种不同政见的人相互辩论，才可以长久保存国家，使国家兴盛强大。也就是说言论自由是民众的基本权利，每个人都可以提出不同的政见，民众有平等参与政治的权利。

I really think a champion is defined not by their wins but by how they can recover when they fall.

唯一能让你成为冠军的是你的专注。

The more you learn, the more you realize how little you know.

Leadership plays a crucial role in diplomacy, and good leadership can guide a team to address complex international challenges.
