If you can't explain it simply, you don't understand it well enough.

翻译：所以善于打仗的人，调动敌人而不被敌人调动。

"We live in time—it holds us and moulds us—but I’ve never felt I understood it very well."

释义：想要夺取什么，必先给予一些什么。

意志不坚强的人，智慧也不会高到哪里去；说话不算数的人，做事也不会果敢痛快。

The poet is not separate from the world; the poet is of the world.
