伟大的精力只是为了伟大的目的而产生的。

Great energy is just for a great purpose.

我是说当我邂逅一部伟大的作品时，却没有时间和精力去细细品味，或者说，我只能大致地浏览一番，对我来说实在是个大遗憾。

But I am saying that it will be really a big pity when I run into a wonderful work I have no time and energy to enjoy it, that is to say, I can only read it superficially.

这些伟大的表演者弄明白了，当他们工作得太久，他们的注意力会分散，他们的精力会衰减，他们的工作会变糟。

These great performers figured out that when they push for too long, their attention wanders, their energy flags, and their work suffers.
