Mr. Youhana, in his book (Live Your Dreams) Les Brown who was an African American writer, and speaker, said , "People's opinion of you do not have to become your reality". I believe that one of the ways we can reach to our success in any walks of life, is by criticism. Also by opinions if they are helpful. Of course there are different types of criticism, and opinions, but sometimes they are negative, and some other times they are positive. This depends on the personality of the person who is criticizing.
