Everybody knows how to criticize but not the art of handling it. Criticism demotivates and causes loss of confidence. It may develop a phobia or anger for the people who has been criticized. Criticism, if taken in the right sense, encourages a person to confound the same people by enhancing themselves or their ideas. This will increase their confidence by many folds. It is a practice which makes them mentally strong.
If we criticize others then we should have heart to help the person and should be ready to handle criticism. The objective of criticism is to better a person or an idea, to make it perfect.Impartial thinking, an optimistic attitude and a never-say-die attitude are ingredients to fight and avoid criticism.
All famous people have faced criticism in their lives and did not allow it to affect them. But only if our eyes saw souls instead the ideal of beauty would have been different. Hence GROW UP and SHOW UP.
