One of the most frequent mistakes we make lies in assuming that personality is a collection of traits, or that a personality is merely the sum of its parts. Personality is a way of organizing these parts...If we look at persons dynamically, and not simply as a static set of traits, we can see that certain defects are the price they pay for their virtues...This is why “pointing out” a bad trait to a colleague or a subordinate - even in a kindly and a well-meaning way - usually does no good, and may even do some harm. It makes him feel worse, and does not enable him to act any better.
