Be ye therefore perfect, eve as your Father who is in heaven is perfect. – Bible

Perfect works are rare, because they must be produced at the happy moment when taste and genius unite; and this rare conjuncture, like that of certain planets, appears to occur only after the revolution of several cycles, and only lasts for an instant. – Vicomte De Chateaubriand

I dont like these cold, precise, perfect people who, in order not to speak wrong, never speak at all, and in order not to do wrong, never do anything. – Henry Ward Beecher
