Better is worse than good enough ~ sucky product manager

In France it's quite common, but with a tweak : "better is good's enemy".

The meaning behind it is that if you let yourself get caught up in an arms race to try and always make what you are trying to do better, you will at some point fuck up and ruin all your previous efforts, and push out something sub-par once you can't just escape forward anymore.

Basically just "don't be to greedy with what you build, or you'll end up with nothing polished enough at the deadline"
