发现的喜悦是科学家们前进的动力。
The joy of discovery is what keeps scientists going.
The man in the planning room, whose specialty under scientific management is planning ahead, invariably finds that the work can be done better and more economically by a subdivision of the labor.
译文:凡是一个人要做一件事情,就必须把全部的精神都集中在这件事情上,从开头到结尾都不能松懈,不可以看到别的就改变主意,做着这件事又想着那件事,坐在这座山上又望着那座山。一个人如果没有恒心,一辈子都不会有什么成就。
