《淮南子·主术训》
如果勉强去做那些自然趋势不允许的事情、不遵循事物客观规律，那么你尽管是圣人神仙也是无法将事情办成功的，又何况你还只是当今的普通君主呢？
夫推而不可为之势，而不修道理之数，虽神圣人不能以成其功，而况当世之主乎！
If you force to do things that the natural trend does not allow, and do not follow the objective laws of things, then even if you are a sage or an immortal, you will not be able to get things done, let alone you are just an ordinary monarch now?
