There is a specific word for criticism that is designed to purposefully assist you. Constructive criticism is the type of criticism in which someone provides feedback on how you do something to help you improve. When somebody does this for you, thank him or her for the advice and follow the instruction you have been presented.
In the field of writting, writers have to look past the criticism; instead they need to analyze the feedback to better their writing abilities. Writing criticism will make writers much more efficient. Appreciate criticisms. People who give criticisms only want the best for you. No matter how self-absorbed you are in thinking that they want only to put you down, think otherwise. You should realize that criticisms are rare opportunities for you to become a better writer. The critiques really provide feedback to care about your growth. It only means that they know that you could have done better as compared to what you have delivered.
When someone presents you more than one piece of advice or critical information, make a list of everything you have learned. Use this list as a set of guidelines to follow to improve your performance.
How should you respond when someone infers you are hopeless or says you will never succeed in your industry or area of study? When you are subjected to this type of criticism, become motivated to work harder and prove the offenders wrong.
There are plenty of critiques that aren't worth the pixels they occupy. Rather than bending your mind around trying to use them to improve your work, or wasting the time feeling offended about them, they should be shelved in the 'useless space' file. These can be positive or negative comments.
