谦逊是伟大领导者的标志。

Wisdom acquisition is a moral duty.It's not something you do just to advance in life...You are not going to get very far in life based on what you already know.You're going to advance in life by what you learn after you leave here.

Success is not final, failure is not fatal: it is the courage to continue that counts.

——《在石家庄国民党交通部欢迎会的演说》（1912年9月21日）

保持领先的唯一途径是不断创新和适应。

最好的建筑是那种消失的、不被注意到的建筑。

文学的美在于它超越时间和空间的能力。
