The problem with perfectionists, albeit not the only one, is that they make mountains out of mole hills. A failure to rise to the occasion. A moment of stupidity. An error that not even an eighteen-year-old rookie writer should or would have made.
After each failure, ask forgiveness, pick yourself up, and try again. Very often what God first helps us towards is not the virtue itself but just this power of always trying again. For however important chastity (or courage, or truthfulness, or any other virtue) may be, this process trains us in habits of the soul which are more important still. It cures our illusions about ourselves and teaches us to depend on God. We learn, on the one hand, that we cannot trust ourselves even in our best moments, and, on the other hand, that we need not despair even in our worst, for our failures are forgiven. The only fatal thing is to sit down content with anything less than perfection. – C.S. Lewis, Mere Christianity
