质量从来不是偶然的；它始终是智慧努力的结果。
Quality is never an accident; it is always the result of intelligent effort.
"The past is not dead; it lives in the stories we choose to remember and retell."
There are unknown forces in nature; when we give ourselves wholly to her, without reserve, she lends them to us; she shows us these forms, which our watching eyes do not see, which our intelligence does not understand or suspect.
