把这一句，留给此刻的你

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

我认为这一点仍然适用于这个行业——基本上是研究和开发——你可能会花更多的时间在计划、培训和设计上，以应对可能出现的问题，以及如何应对这些问题，而不是花更多的时间去做正确的事情。
