There are some strange dynamics to literary criticism.
The people who are most qualified to criticise—editors and agents—will usually not be eager to comment, while the people who are the least qualified—your mum or your best friend—will bite your head off for an opportunity to read and comment on your work.
When you receive criticism, this odd dynamic remains: editors and agents are likely to find fault with your work while your mother is likely to tell you how wonderful it is.
These dichotomies are paralleled by most writers’ reactions to criticism. The better or more experienced a writer is, the more likely he is to value the opinion of his editor and the less weight he’ll give to his mother’s proud comments.
Novice writers, however, insist that such editors just haven’t understood their work, and anyway—their mum loves it.
