Matrix movie quote question: Advice on saying/translating "There is a difference in knowing the path and walking the path"? I know how Google Translate translates this, but wondering how those who actually use Mandarin/Chinese would say it.

Thank you very much in advance.
There is a difference in knowing the path and walking the path

The idiom 知易行難 (knowing how to do something is easy; put it into action is hard) match this quote quite well
知 - know; aware
易 - easy
行 - implement; walk
難 - difficult
The writer might know this idiom but thought 行 meant walk
To put this idiom into quote:
正所謂「知易行難」
你知道「知易行難」的道理嗎?
古語有云 「知易行難」
To translate the quote from Matrix directly, you can say  &quot;知道路怎麼走和真的去走這條路是有分別的&quot; (There is a difference between knowing the path and really walking the path)

The elegant way to say it is &quot;说時容易做時难&quot;, which is a common expression
