Criticism is just normal in a workplace. Positive criticism should be taken as they are and negative criticism should be taken as a challenge so we can improve ourselves more, and let our colleagues (especially the critics) see how effective and efficient we are in our jobs. By taking these negative criticisms in a positive way, we make ourselves more enthusiastic in doing our job. What matters is that, we have a good job record. This way we continue to strive and reach for our ambition to succeed.
