Many years ago, I heard a politician give a speech, and he used a phrase there (I am translating from German, so it might sound a little clumsy): The worst enemy of Good is Better.

Over time, I have come to believe that the worst enemy of Better is "Good Enough".

A comparable English expression is “the perfect is the enemy of the good”, which I think every software engineer should have engraved on to their monitors as a reminder.

A slightly different twist, but also a popular idiom, is that "excellence is good enough".

The common English idiom I’ve heard that is similar to the 2nd one is “‘Good Enough’ never is”, which is grammatically a bit strange but a fun one.
