Criticism, commonly taken as a synonym for disapproval expressed by pointing out one's faults, can actually be a thoughtful analysis if done constructively. Constructive criticism is an expression of compassion towards the person whose work one is criticizing. Constructive critics often have a healthy relationship with the person they qualify for criticism. The cordial relationship between the critic and the criticized helps both the parties handle criticism in the right way.
Criticism in a form of giving/receiving unintentional yet hurtful judgments that may be difficult for the critic to give and for the criticized to receive. But if taken in the right spirit, it can actually help. Constructive criticism can be referred to as the critical evaluation of a piece of work. It involves a thorough analysis of a piece of work and helps improve it.
The critic should understand the reason behind the criticism. It is not correct to criticize something just for the heck of it. The knowledge of the field of work and the expertise in the field gives a person the right to criticize. One should criticize a piece of work only if he or she has complete knowledge of the subject dealt with, in the piece. Shallow information about a subject, mere know-how of certain things surrounding the subject, or a biased approach are detrimental to constructive criticism.
Criticize the work, not the person. If a person's behavior is to be criticized, do only that and avoid blaming the person for other things. It is not right to get personal while criticizing. It becomes heartbreaking for the person accepting it and can spoil the relations between the critic and the criticized. Invite discussion rather than offering advice and keep the criticism open for two-way dialog. Emphasize on the present times rather than giving references of the past. Even if it's constructive criticism, but do not overdo it.
It is absolutely necessary for you to be prepared for accepting criticism. Your right to criticize implies the fact that you can be criticized too. Learn to be sportive enough to receive criticism. Like your constructive criticism can help someone, someone else's can help you too. Most of us hate being criticized. We think of criticism as something that attacks our self-esteem. However, the truth is that constructive criticism can help us know our shortcomings. It can help us get a better picture of our strengths and weaknesses.
Parents and teachers often take to constructive criticism to help their children or students improve. Imagine never being criticized by an elder. Think of your life without that element of criticism. How would it have been? Would you have become what you are today? Would you have been able to work on your weaknesses if you were never made aware of them? Would you have been able to correct your flaws if no one would have pointed them out to you? I am sure none of us would have achieved what we have, without facing criticism. If not for constructive criticism that made us understand ourselves, I don't think anyone of us would have been able to correct our mistakes.
So the next time you are criticized for something, do not feel discouraged. Be grateful to your critics.
