"大多数决策是双向的门。如果你做出了错误的选择，你可以走出来，选择另一扇门，再次尝试。你花一点时间在第一个选择上，意识到它不对，然后继续前进。然而，有些决策是单向的门。这些决定具有重大影响力且难以逆转。一旦你通过了，就无法回头。这些决策必须慎重和谨慎地做出。如果有其他方法可以分析它们，你应该放慢速度并花时间去做。"

Simplified Meaning:

Many choices in life are like doors you can walk through and, if you don’t like what’s on the other side, you can turn around and come back out. For example, trying out a new hobby is a two-way door. If you start painting and later decide it's not for you, you can simply stop and try something else, like cooking or playing a musical instrument. This type of choice doesn't carry significant risks because you can always reverse it. On the other hand, some choices are like one-way doors. Once you step through, there is no turning back. Think about moving to a different country or deciding to have a child. These decisions have lifelong consequences and are very hard, if not impossible, to undo. Because of their importance, it's crucial to think them through very carefully. Take your time to weigh all options and consider the long-term impact before making such decisions. Slowing down and analyzing these big choices can help ensure that you make the best possible decision for your future.
