Not good to get always criticized since it cam drain out our energy since we would think about that we don't do any good on the careers we do. But you should also seek the reason why people criticize you since from this maybe you will get an idea about what are the things you need to fix and enhance so that you can do more better then next time you would earn praises coming from your colleague's. We need to work more to enhance our knowledge on something we are interested to broad up our knowledge and that can help us gain more profit in future.
That can also be said for criticism. When you are overly and unduly critisized, you will tend to lose your confidence and self esteem.
if we receive too much criticism in everything we do it means we need to pause from our activities and evaluate what is wrong with us. we have to be able to find out what is wrong with us when we always receive criticism.
in essence we should not be selfish and always be open to criticism from others in the learning process because criticism is a process to recognize and correct our mistakes.
