Perfect is the Enemy of Good

Perfect is the enemy of good is an aphorism or proverb which is commonly attributed to Voltaire whose moral poem, La Bégueule, starts

Dans ses écrits, un sàge 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)

The moral is that perfectionism is contrary to a satisfactory competence. Aristotle, Confucius and other classical philosophers propounded the principle of the golden mean which counsels against extremism in general. The Pareto principle or 80–20 rule explains this numerically. For example, it commonly takes 20% of the full time to complete 80% of a task while the last 20% takes 80% of the effort. Achieving absolute perfection may be impossible and so, as increasing effort results in diminishing returns, further activity becomes increasingly inefficient.
