实现明天的唯一限制将是我们今天的怀疑。
"The only limit to our realization of tomorrow will be our doubts of today."
The true delight is in the finding out rather than in the knowing.
世界上充满了显而易见的事物,却没有人注意到它们。
I was told I had the voice of a choirboy but the look of a headmistress.
"Words are the footprints of the mind."
