明显的？可能。有时，只有一旦您被证明是这样，常识才是显而易见的。只有在揭示了捷径之后，这是一个明显的节省时间。在此之前，除了开明的人以外，它仍然完全不知道。你不知道你不知道的东西，因此，永远不要寻求任何人的辅导
(Obvious? Possibly. Sometimes, common sense is only obvious once you have been shown it to be so. Only after a shortcut has been revealed is it an obvious time saver. Before that, it had remained completely unknown to everyone but the enlightened. You can't know what you don't know and, therefore, never seek anyone's tutorage of the subject)
