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, that we need not despair even in our worst, for our failures are forgiven.

(Speaking on pride) There is no fault which makes a man more unpopular, and no fault which we are more unconscious of in ourselves. And the more we have it in ourselves, the more we dislike it in others.
- Book 3 Chapter 8 The Great Sin
A proud man is always looking down on things and people: and, of course, as long as you are looking down, you cannot see something that is above you.
