The most dangerous poison is the feeling of achievement. The antidote is to think like a beginner every morning.
除非不再尝试，否则就没有失败。
《致全国学农工商通电》（1924年4月12日）
我们把客户视为受邀参加派对的客人，而我们是主人。我们的工作是每天让客户体验的每一个重要方面都变得更好一点。
自然是最伟大的智者。
The artist must be a witness to the mystery.
The only person you should try to be better than is the person you were yesterday.
