It is, though I think they can be reversed while meaning the same thing. As for the whole “Why I decided on the inversion”: I’ve got no idea. It sounded right in context (in my head) and I should have googled it quickly to make sure I had the phrase right. My bad.

It's funny that when a phrase is used enough, it stops just being it's constituent parts. In this case, the inversion has no effect on the meaning.

“Good is the enemy of perfect” would mean just trying to make something good enough means it will probably not be perfect. Which…ok…makes sense. I’ll have to run that by RPG next time I see him.

Isn't someone naturally their enemies enemy? It seems commutative.
