Sometimes in life, you don't always feel strong, but that doesn't mean you're not.

The opening up of new markets, foreign or domestic, and the organizational development from the craft shop and factory to such concerns as U.S. Steel illustrate the same process of industrial mutation—if I may use that biological term—that incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one.

成功不是终点，失败也不是致命的：重要的是继续前进的勇气。

好弓难以拉开，然而可以射得高射得深；良马难以驾御，然而可以负重行远。

最好的作品是那些无法解释的作品。

【解释】浓烈、肥腻、辛辣的刺激不是本真滋味，平淡自然才是真实的生活；才智超凡的人，不是完美的人，真正的完人，看起来平凡无奇。
