How to handle rejection slips
Realize you are not alone.
It might feel that way when you open the envelope, and the words on the page may sting your ego, but you are in good company. Even the most famous authors who have gotten rich had their share of rejection.
Understand that the rejection slip isn't personal. There are multiple reasons why your work may have been rejected, such as a similar piece may have already been bought, the tone wasn't quite right or the editor was simply having a bad day.
