Criticism is about getting and giving feedback which can lead to increased performance. Criticism (finding fault with our behavior) and emotions are related topics because criticism tends to bring out feelings, as people tend to get emotional and defend their behavior. So when we deal with criticism, we tend to have to deal with emotions.

It is great to hear praise for the job we are doing, and we need to hear it as a motivator, but the only way we can improve is to openly seek criticism. However, if you ask someone for critical feedback, remember that you are asking to hear things that may surprise, upset, or insult you, or hurt your feelings. We do not really enjoy being criticized, even when it is constructive, and many people handle criticism poorly. Ask your boss the best way to check in on how you're doing, including how often and which channel to use for feedback.

Many managers will not tell you how they really view your performance, so if you want to advance, you need to ask them without getting defensively emotional. Even when you think the feedback is wrong, look for ways to improve. During a performance review, if you don't get the rating you want, ask what “specifically” you need to do to get the higher rating during the next review period—and do it.

Don't take it personally or react emotionally. Focus on the positive side, realizing that the feedback can lead to improved performance. Also, admitting your lack of exceptional performance and working to improve will improve your relationship with your boss.
