Few people are harder to deal with than those impervious to advice and unwilling to listen.

Such people don't know how to accept others' criticism, nor do they criticize others, and they retain a strong sense of pride. For someone who wants to criticize them, one can only continually increase the tactfulness of the criticism in an attempt to influence them. Yet they, as perfectionists, pride themselves on being very willing to accept others' opinions. Faced with harsh criticism, they feel as if the world is ending — either because they think they're worthless, or because they believe everyone dislikes them, or both; with mild criticism, they become even less receptive. They also won't criticize others, acting like a goody-goody. What could be more despairing than such a personality?

Accept others' criticism; realize it's not the end of the world, you're not worthless, and people aren't universally against you. Maintain a normal mindset, provide feedback after receiving criticism, and interpersonal relations become very simple.

Give others criticism to let them know you haven't ignored them. Offer sincere, issue-focused suggestions; stick to the matter at hand.

Inwardly, remain true to yourself and accept criticism; outwardly, remain true to yourself and offer criticism.

The perfect fusion of reason and feeling together determines a person's depth.
