The perfect is the enemy of the good is an aphorism or proverb meaning that insisting on perfection often results in no improvement at all. The phrase is commonly attributed to Voltaire whose moral poem, La Bégueule, starts[1]
“Dans ses écrits, un sage Italien
Dit que le mieux est l’ennemi du bien.
(In his writings, a wise Italian
says that the best is the enemy of the good)
