"Pleasure in being praised is not Pride. The child who is patted on the back for doing a lesson well, the woman whose beauty is praised by her love, the saved soul to whom Christ says 'Well done,' are pleased and ought to be. For here the pleasure lies not in what you are but in the fact that you have pleased someone you wanted (and rightly wanted) to please. The trouble begins when you pass from thinking 'I have pleased him; all is well.' to thinking, 'What a fine person I must be to have done it.' The more you delight in yourself and the less you delight in the praise, the worse you are becoming. When you delight wholly in yourself and do not care about the praise at all, you have reached the bottom. That is why vanity, though it is the sort of Pride which shows most on the surface, is really the least bad and most pardonable sort. The vain person wants praise, applause, admiration, too much and is always angling for it. It is a fault, but a child-like and even (in an odd way) a humble fault. It shows that you are not yet completely contented with your own admiration. You value other people enough to want them to look at you. You are, in fact, still human."
